Alpaca

The Alpaca (Vicugna pacos) is a domesticated species of South American camelid. It resembles a small llama in superficial appearance.
Alpacas are kept in herds that graze on the level heights of the Andes of Ecuador, southern Peru, northern Bolivia, and northern Chile at an altitude of 3,500 m (11,483 ft) to 5,000 m (16,404 ft) meters above sea-level, throughout the year.[citation needed] Alpacas are considerably smaller than llamas, and unlike llamas, alpacas were not bred to be beasts of burden but were bred specifically for their fiber. Alpaca fiber is used for making knitted and woven items, much as sheep's wool is. These items include blankets, sweaters, hats, gloves, scarves, a wide variety of textiles and ponchos in South America, and sweaters, socks, coats and bedding in other parts of the world. The fiber comes in more than 52 natural colors as classified in Peru, 12 as classified in Australia and 16 as classified in the United States. Alpacas and llamas differ in that alpacas have straight ears and llamas have banana-shaped ears. Aside from these differences, llamas are on average 1-2 feet taller and proportionally bigger than alpacas.
In the textile industry, "alpaca" primarily refers to the hair of Peruvian alpacas, but more broadly it refers to a style of fabric originally made from alpaca hair but now often made from similar fibers, such as mohair, Icelandic sheep wool, or even high-quality English wool.[citation needed] In trade, distinctions are made between alpacas and the several styles of mohair and luster.

Alpacas are social herd animals that live in family groups consisting of a territorial alpha male, females and their young. They are gentle, inquisitive, intelligent and observant. As they are a prey animal, they are cautious and nervous if they feel threatened. They like having their own space and may not like an unfamiliar alpaca or human getting close, especially from behind. They warn the herd about intruders by making sharp, noisy inhalations that sound like a high pitch burro bray. The herd may attack smaller predators with their front feet, and can spit and kick. Due to the soft pads on their feet, the impact of a kick is not as dangerous as that of a hoofed animal, yet it still can give quite a bruise, and the pointed nails can inflict cuts.

Aye-Aye

The Aye-aye (Daubentonia madagascariensis) is a strepsirrhine native to Madagascar that combines rodent-like teeth with a long, thin middle finger to fill the same ecological niche as a woodpecker. It is the world's largest nocturnal primate, and is characterized by its unusual method of finding food; it taps on trees to find grubs, then gnaws holes in the wood and inserts its elongated middle finger to pull the grubs out. The only other animals known to find food in this way is the Striped Possum.[citation needed] From an ecological point of view the Aye-aye fills the niche of a woodpecker as it is capable of penetrating wood to extract the invertebrates within.
Daubentonia is the only genus in the family Daubentoniidae and infraorder Chiromyiformes. The Aye-aye is the only extant member of the genus (although it is currently classified as Near Threatened by the IUCN); a second species, Daubentonia robusta, appears to have become extinct at some point within the last 1000 years.

The Aye-aye is the world's largest nocturnal prosimian, and dwells predominantly in forest canopies. It weighs about 2.5 kilograms, with the female weighing in slightly less (by an average of 100 grams) than males. Other than weight and sex organs, aye-ayes exhibit no sexual dimorphism of any kind. They all grow from 30-37 cm from head to body, with a 44-53 cm tail.
The adult Aye-aye has black or dark brown fur covered by white guard hairs at the neck. The tail is bushy and shaped like that of a squirrel. The Aye-aye's face is also rodent-like, the shape of a raccoon's, and mouses bright, beady, luminous eyes. Its incisors are very large, and grow continuously throughout its lifespan. These features contrast its monkey-like body, and are the likely cause of why scientists originally deemed it to be a rodent.
The Aye-aye's hands are arguably its most unusual feature. Much like other primates, it possesses opposable thumbs, but both the hallux and the fingers are long and slender, and appear to be in a curved position somewhat similar to that of a fairy-tale witch when the muscles are relaxed.[clarification needed] The middle finger can be up to three times longer than the others.
Gestation for the Aye-aye lasts from 5 to 5 1/3 months. Births can occur at any time during the year, and females often wait 2-3 years between births. The infant takes about 7 months to be weaned, and stays with its mother for two years. The Aye-aye matures quickly; males rarely take more than 1 1/2 years to mature, and females take about an extra year. Lifespan is not known, but the world record is 23 years in captivity.

The Aye-aye lives primarily on the east coast of Madagascar. Its natural habitat is rainforest or deciduous forest, but many live in cultivated areas due to deforesting. Rainforest Aye-ayes, the most common, dwell in canopy areas, and are usually sighted upwards of 700 meters altitude. The Aye-aye sleeps during the day in nests built in the forks of trees.

Axolotl

The axolotl, Ambystoma mexicanum, is the best known of the Mexican neotenic mole salamanders belonging to the Tiger Salamander complex. Larvae of this species fail to undergo metamorphosis, so the adults remain aquatic and gilled. The species originates from the lake underlying Mexico City and is also called ajolote (which is also the common name for the Mexican Mole Lizard). Axolotls are used extensively in scientific research due to their ability to regenerate most body parts, ease of breeding, and large embryos. They are commonly kept as pets in the United States, Great Britain (under the spelling axlotl), Australia, Japan (sold under the name wooper rooper) and other countries.
Axolotls should not be confused with waterdogs, the larval stage of the closely related Tiger Salamanders (Ambystoma tigrinum and Ambystoma mavortium), which are widespread in much of North America and also occasionally become neotenic, nor with mudpuppies (Necturus spp.), fully-aquatic salamanders which are not closely related to the axolotl but bear a superficial resemblance.
As of 2008, wild axolotls are near extinction due to urbanization in Mexico City and polluted waters. Nonnative fish such as African tilapia and Asian carp have also recently been introduced to the waters. These new fish have been eating the axolotls' babies, as well as its primary source of food. The axolotl is currently on the International Union for Conservation of Nature's annual Red List of threatened species.

A sexually mature adult axolotl, at age 18-24 months, ranges in length from 15–45 centimetres (5.9–18 in), although a size close to 23 centimetres (9.1 in) is most common and greater than 30 centimetres (12 in) is rare. Axolotls possess features typical of salamander larvae, including external gills and a caudal fin extending from behind the head to the vent. Their heads are wide, and their eyes are lidless. Their limbs are underdeveloped and possess long, thin digits. Males are identified by their swollen cloacae lined with papillae, while females are noticeable for their wider bodies full of eggs. Three pairs of external gill stalks (rami) originate behind their heads and are used to move oxygenated water. The external gill rami are lined with filaments (fimbriae) to increase surface area for gas exchange. Four gill slits lined with gill rakers are hidden underneath the external gills. Axolotls have barely visible vestigial teeth, which would have developed during metamorphosis. The primary method of feeding is by suction, during which their rakers interlock to close the gill slits. External gills are used for respiration, although buccal pumping (gulping air from the surface) may also be used in order to provide oxygen to their lungs. Axolotls have four different colours, two naturally occurring colours and two mutants. The two naturally occurring colours are wildtype (varying shades of brown usually with spots) and melanoid (black). The two mutant colours are leucistic (pale pink with black eyes) and albino (golden, tan or pale pink with pink eyes).

Pink Fairy Armadillo

The Pink Fairy Armadillo (Chlamyphorus truncatus) or Pichiciego is the smallest species of armadillo (mammals of the family Dasypodidae, mostly known for having a bony armor shell.
The Pink Fairy Armadillo is approximately 90-115 mm (3½-4½") long excluding the tail, and is pale rose or pink in color. It is found in central Argentina where it inhabits dry grasslands and sandy plains with thorn bushes and cacti. It has the ability to bury itself completely in a matter of seconds if frightened.
The Pink Fairy Armadillo burrows small holes near ant colonies in dry dirt. It feeds mainly on ants and ant larvae near its burrow. Occasionally it feeds on worms, snails, insects and larvae, or various plant and root material.

Proboscis Monkey

The Proboscis Monkey (Nasalis Lavartus) sometimes known as "the Gerard" in America. In native lands it is formally termed the Bekantan in [[Indonesian languageIndonesian] and colloquially the Monyet Belanda in Indonesian and the Malay dialect [literally: "Dutchman monkey"]. In English it can be referred to as Nasalis Gerardis and the Long-nosed Monkey.Previous biologists termed the Nastalis Lavartus the Nasalis capistratus (Kerr in 1792), Nasalis nasica (Lacépède in 1799) and Nasalis recurvus by Vigors & Horsfield in 1828.
The Nasalis Larvartus is a reddish-brown arboreal (tree-dwelling) Old World monkey that is endemic to the South-East Asian island of Kalimantan commonly known in English as Borneo. The Nasalis Lavartus belongs in the monotypic genus 'Nasalis, although the Pig-tailed Langur has traditionally also been included in this genus - a treatment still preferred by some.

There are two contested sub-species which not all authorities recognize as separate: the Nasalis larvatus ssp. larvatu inhabiting everywhere but northeastern Kalimantan and the Nasalis larvatus ssp. orientalis restricted to northeastern Kalimantan, Indonesia.

Proboscis monkeys belong to the order of Primates, from the family Cercopithecidae and subfamily Colobinae.A distinctive trait of this monkey is the male's large protruding proboscis or nose, from which it takes its name. The big nose is thought to be used to attract females and is a characteristic exclusively of the male growing up to 15 cm (7 inches) in length. The females also have big noses compared to other monkey species, but not as big as the males. Besides attracting mates, the nose serves as a resonating chamber, amplifying their "honking" warning calls. When the animal becomes agitated its nose swells with blood, making warning calls louder and more intense.[7]
The adult Proboscis Monkey is mainly reddish-brown, with grayish limbs (Bennett & Gombek, 1993). According to Burnie (2001), the young Proboscis Monkey have blue face, blackish fur and a smallish nose at birth. As it grows, its' fur coloration changes and the nose increases in size. The Indonesian and Malay peoples subversively coined the Nasalis Lavartus the: "Monyet Belanda" [literally: Dutchman monkey] for the perceived resemblance to the Dutch and later British colonials specifically the long, red nose, the red complexion of the "face" and the tendency for fur especially of the cranium and area of face homologous to sideburns to be red or yellow. Some also suggest the colonials language sounded like the Lavartus honking to the native Malaysians and Indonesians.

Star-nosed Mole

The star-nosed mole (Condylura cristata) is a small North American mole found in eastern Canada and the north-eastern United States. It is the only member of the tribe Condylurini and the genus Condylura.

The incredibly sensitive nasal tentacles are covered with minute touch receptors known as Eimer's organs. The nose is approximately one centimeter in diameter with approximately 25,000 Eimer's organs distributed on 22 appendages. Eimer's organs were first described in the European mole in 1871 by German zoologist Theodor Eimer. Other mole species also possess Eimer's organs, though they are not as specialized or numerous as in the star-nosed mole. Because the star-nosed mole is functionally blind, it had long been suspected that the snout was used to detect electrical activity in prey animals, though there is little, if any, empirical support for this contention. It appears the nasal star and dentition of this species are primarily adapted to exploit extremely small prey items. A report in the journal Nature gives this animal the title of fastest-eating mammal, taking as short as 120 milliseconds (average: 227 milliseconds) to identify and consume individual food items. Its brain decides in the ultra short time of 8 ms if a prey is comestible or not. This speed is at the limit of the speed of neurons. They also possess the ability to smell underwater. It is done by exhaling air bubbles onto objects or scent trails and then inhaling the bubbles to carry the smell back through the nose.

Hagfish

Hagfish are marine craniates of the class Myxini, also known as Hyperotreti. Myxini is the only class in the clade Craniata that does not also belong to the subphylum Vertebrata. That is, they are the only animals which have a skull but not a vertebral column.
Despite their name, there is some debate about whether they are strictly fish (as there is for lampreys), since they belong to a much more primitive lineage than any other group that is placed in the category of fish (Chondrichthyes and Osteichthyes). Their unusual feeding habits and slime-producing capabilities have led members of the scientific and popular media to dub the hagfish as the most "disgusting" of all sea creatures. Although hagfish are sometimes called "slime eels," they are not eels at all.

Hagfish average about half a meter (18 in) long; The largest known species is Eptatretus goliath with a specimen recorded at 127 cm, while Myxine kuoi and Myxine pequenoi seem to reach no more than 18 cm.
Hagfish have elongated, eel-like bodies, they have four hearts and two brains[citation needed], and paddle-like tails. They have cartilaginous skulls and tooth-like structures composed of keratin. Colours depend on the species, ranging from pink to blue-grey, and black or white spots may be present. Eyes are simple eyespots, not compound eyes that can resolve images. Hagfish have no true fins and have six or eight barbels around the mouth and a single nostril. Instead of vertically articulating jaws like Gnathostomata (vertebrates with jaws), they have a pair of horizontally moving structures with tooth-like projections for pulling off food.

Tapir

Tapirs are large browsing mammals, roughly pig-like in shape, with short, prehensile snouts. They inhabit jungle and forest regions of South America, Central America, and Southeast Asia. All four species of tapir are classified as endangered or vulnerable. Their closest relatives are the other odd-toed ungulates, including horses and rhinoceroses.

Size varies between types, but most tapirs are about 2 meters (7 ft) long, stand about a meter (3 ft) high at the shoulder, and weigh between 150 and 300 kg (330 to 700 lb). Coats are short and range in color from reddish-brown to grey to nearly black, with the notable exceptions of the Malayan Tapir, which has a white saddle-shaped marking on its back, and the Mountain Tapir, which has longer, woolly fur. All tapirs have oval, white-tipped ears, rounded, protruding rumps with stubby tails, and splayed, hoofed toes, with four toes on the front feet and three on the hind feet, which help them walk on muddy and soft ground. Baby tapirs of all types have striped-and-spotted coats for camouflage. Females have a single pair of mammary glands.

White-faced Saki Monkey

The White-faced Saki (Pithecia pithecia), also known as the Guianan Saki and the Golden-faced Saki, is a species of saki monkey, a type of New World monkey, found in Brazil, French Guiana, Guyana, Suriname, and Venezuela. This species lives in the understory and lower canopy of the forest, feeding mostly on fruits, but also eating nuts, seeds, and insects.


In captivity, female White-faced Sakis experience ovarian cycles of approximately 17 days, and a gestational period of 20-21 weeks. Following birth, the mother undergoes a period of lactationally-induced fertility lasting 23 weeks, on average.


Sakis of the Pithecia pithecia species display noticeable sexual dimorphism in their coloration. Females have shorter hair than males, with brownish-grey fur and white or pale brown stripes around the corners of the nose and mouth. Males, on the other hand, have blacker fur, with a reddish-white forehead, face, and throat.

Emperor Tamarin

The Emperor Tamarin (Saguinus imperator) is a tamarin allegedly named for its resemblance to the German emperor Wilhelm II. It lives in the southwest Amazon Basin, in east Peru, north Bolivia and in the west Brazilian states of Acre and Amazonas.



The fur of the Emperor Tamarin is predominantly grey colored, with yellowish speckles on its chest. The hands and feet are black and the tail is brown. Outstanding is its long, white mustache, which extends to both sides beyond the shoulders. The animal reaches a length of 24 to 26 cm (9 1/2 to 10 1/4 in), plus a 35 cm (13 3/4 in) long tail. It weighs approximately 300 to 400 g (10 1/2 to 14 oz). This primate inhabits tropical rain forests, living deep in the forest and also in open tree-covered areas. This diurnal species walks or runs quadrupedally through the forest, spending the majority of its days in the trees with quick, safe movements and broad jumps among the limbs.



The Emperor Tamarin lives together in groups of two to eight animals. The oldest female leads the group above several mature males. Mutual grooming plays an important role for bonding and socializing. The Emperor Tamarin is known to form mixed-species associations with the Brown-mantled Tamarin (Saguinus fuscicollis). It has various cries which help them to promptly recognize interlopers.

The diet of the Emperor Tamarin is similar to that of other tamarins. It is an omnivore, primarily eating fruits, insects and sap. When feeding on sap, the Emperor Tamarin latches on to the tree vertically with its claws dug into the bark of the tree. It also eats bird eggs and small vertebrates (such as tree frogs). Due to its small weight it can reach food at the far end of branches, which are not accessible to heavier animals.

The Emperor Tamarin lives a polyandrous life, i.e. the mature female mates with all of the males of her harem. Gestation is 140 to 145 days, and births are typically twins (although triplets happen on occasion) as is typical of tamarins. All the males, father or not, help with the birth, care, and support of the young, carrying them and bringing them to the mother to nurse. At approximately three months they are weaned, and toward the end of the second year they are fully mature. The Emperor Tamarin's life expectancy is over 15 years. Very little is known about the population of Emperor Tamarin in the wild.

Sloth

The living sloths comprise six species of medium-sized mammals that live in Central and Sout America belonging to the families Megalonychidae and Bradypodidae, part of the order Pilosa. The sloth's taxonomic suborder is Folivora, while some call it Phyllophaga. Both names mean "leaf-eaters"; the first is derived from Latin, the second from ancient Greek. Tribal names include Ritto, Rit and Ridette, mostly forms of the word "sleep", "eat" and "dirty" from Tagaeri tribe of Huaorani.



Until geologically recent times,ground sloths such as Megatherium lived in South America and parts of North America, but along with many other animals they disappeared immediately after the arrival of humans on the continent Much evidence suggests that human hunting contributed to the extinction of the American megafauna, like that of far northern Asia, Australia, New Zealand, and Madagascar. Simultaneous climate change that came with the end of the last Ice age may have also played a role in some cases. However, the fact that ground sloths survived on the Antilles long after they had died out on the mainland points towards human activities as the agency of extinction.

The living sloths are omnivores. They may eat insects, small lizards, and carrion, but their diet consists mostly of buds, tender shoots, and leaves, mainly of Cecropia trees. They have made extraordinary adaptations to an arboreal browsing lifestyle. Leaves, their main food source, provide very little energy or nutrition and do not digest easily. Sloths therefore have very large, specialized, slow-acting stomachs with multiple compartments in which symbiotic bacteria break down the tough leaves. As much as two-thirds of a well-fed sloth's body-weight consists of the contents of its stomach, and the digestive process can take a month or more to complete.
Even so, leaves provide little energy, and sloths deal with this by a range of economy measures: they have very low metabolic rates (less than half of that expected for a creature of their size), and maintain low body temperatures when active (30 to 34 °C or 86 to 93 °F), and still lower temperatures when resting.
Although unable to survive outside the tropical rainforests of South and Central America, within that environment sloths are outstandingly successful creatures: they can account for as much as half the total energy consumption and two-thirds of the total terrestrial mammalian biomass in some areas. Of the six living species, only one, the Maned Three-toed Sloth (Bradypus torquatus), has a classification of "endangered" at present. The ongoing destruction of South America's forests, however, may soon prove a threat to other sloth species.

Red Panda

The Red Panda, also called the Firefox or Lesser Panda (Latin name: Ailurus fulgens, "shining cat"), is a mostly herbivorous mammal, specialized as a bamboo feeder. It is slightly larger than a domestic cat (40 - 60 cm long, 3 - 6 kg weight). The Red Panda is endemic to the Himalayas in Bhutan, southern China, Pakistan, India, Laos, Nepal, and Burma. There is an estimated population of fewer than 2,500 mature individuals. Their population continues to decline due to habitat fragmentation.

Recent molecular-systematic DNA research places the Red Panda into its own independent family Ailuridae. Ailuridae are in turn part of a trichotomy within the broad superfamily Musteloidea (Flynn et al., 2001) that also includes the Mephitidae (skunks) and the Procyonidae (raccoons) + Mustelidae (weasels). Unlike the Giant Panda, it is not a bear (Ursidae).
There are two extant subspecies of Red Panda: the Western Red Panda (Ailurus fulgens fulgens) that lives in the western part of its range, and the somewhat larger Styan's Red Panda (Ailurus fulgens styani) that lives in the east-northeastern part of its range. The Western Red Panda has lighter pelage, especially in the face, while the Styan's Red Panda has more dramatic facial markings. The effective population size in the Sichuan population is larger and more stable than that in the Yunnan population, implying a southward expansion from Sichuan to Yunnan.
The taxonomic classification of both the Red Panda and Giant Panda has been under debate for many decades, as both species share characteristics of both bears and raccoons. However, they are only very distantly related by remote common ancestry from the Early Tertiary Period. Its common ancestor can be traced back to tens of millions of years ago with a wide distribution across Eurasia. Fossils of the Red Panda have been unearthed from China in the east to Britain (Parailurus anglicus) in the west (Hu, 1990,Ro), and most recently a handful of fossils(Pristinailurus bristoli, Miocene, considered to be a new genus and species of the Red Panda) have also been discovered in North America.

Angora Rabbit

The Angora rabbit is a variety of domestic rabbit bred for its long, soft hair. The Angora is one of the oldest types of domestic rabbit, originating in Ankara, Turkey, along with the Angora cat and Angora goat. The rabbits were popular pets with French royalty in the mid 1700s, and spread to other parts of Europe by the end of the century. They first appeared in the United States in the early 1900s. They are bred largely for their long angora wool, which may be removed by shearing, combing, or plucking (gently pulling loose wool).
There are many individual breeds of Angora rabbits, four of which are ARBA recognized. Such breeds include French, German, Giant, English, Satin, Chinese, Swiss and Finnish, to name a few.

Angoras are bred mainly for their wool because it is silky and soft. They have a humorous appearance, as they oddly resemble a fur ball. Most are calm and docile but should be handled carefully. Grooming is necessary to prevent the fiber from matting and felting on the rabbit. Because they are prone to hairballs, they should be groomed everyday or every other day. A condition "wool block" is common in angora rabbits and should be treated quickly. Sometimes they are shorn in the summer as the long fur can cause the rabbits to overheat.

Sun Bear

The Sun Bear (Helarctos malayanus) is a bear found primarily in the tropical rainforests of Southeast Asia. Its Malay and Indonesian name is Beruang Madu ("Honey Bear").

The Sun Bear stands approximately 1.2 m (4 ft) in length, making it the smallest member in the bear (Ursidae) family. Males tend to be 10-45% larger than females; the former normally weigh between 30 and 60 kg (66-132 lb), the latter between 20 and 40 kg (44-88 lb). The Sun Bear possesses sickle-shaped claws that are relatively light in weight. It has large paws with naked soles, probably to assist in climbing. Its inward-turned feet make the bear's walk pigeon-toed, but it is an excellent climber. It has small, round ears and a stout snout. The tail is 1.2-2.8 inches (3-7 cm) long. Despite its small size, the Sun Bear possesses a very long, slender tongue, ranging from 8 to 10 inches (20-25 cm) in length. The bear uses it to extract honey from beehives.
Unlike other bears, the Sun Bear's fur is short and sleek. This adaptation is probably due to the lowland climates it inhabits. Dark black or brown-black fur covers its body, except on the chest, where there is a pale orange-yellow marking in the shape of a horseshoe. Similar colored fur can be found around the muzzle and the eyes. These distinctive markings give the Sun Bear its name.

The diet of the Sun Bear varies widely and includes small vertebrates, such as lizards, birds, and other mammals, in addition to fruits, eggs, termites, the young tips of palm trees, nests of bees, berries, sprouts, insects, roots, cocoa, and coconuts. Its powerful jaws can crack open nuts. Much of the Sun Bear's food must be detected using its keen sense of smell, as its sight is poor. They live to about 28 years in captivity.

The Sun Bear does not hibernate, and, as a result, it can reproduce year-round. The offspring reach sexual maturity after 3-4 years and may live up to 28 years in captivity. A female Sun Bear can produce 1 to 2 cubs per year. Sun Bears undergo a roughly 96 day gestation period after which the 300 to 400g cub is born blind and hairless. The cub is initially totally dependent on its mother and suckling can continue for about 18 months. After 1 to 3 months, the young cub can run, play and forage near its mother. Male Sun Bears grow larger than females. Females are observed to mate at about 3 years. During time of mating, the Sun Bear will show behavior like hugging, mock fighting and head bobbing with its mate.
Being a primarily nocturnal creature, the Sun Bear tends to rest during the day on lower limbs not far above the ground. Because it spends so much time in trees, the Sun Bear can sometimes cause a good amount of damage to private property. It has been known to destroy coconut palms and cacao trees on plantations.

Adult Sun Bears have almost no predators except humans, due to their fierce reputation and formidable teeth. Occasionally, they may be overwhelmed by tigers, or large reticulated pythons. Possible predators include the leopard, the clouded leopard, and the Sun Bear's larger sympatric relative, the Asiatic Black Bear. The bear's loose skin on its neck allows it to wriggle its body inside its skin far enough to turn around and bite its attacker when grabbed.
The recent decline in the Sun Bear population can be largely attributed to the hunting of "nuisance bears" that destroy crops and poaching driven by the market for their fur and for their bile, which is used in Chinese medicine.
Sometimes, Sun Bears are captured or bred to be domestic pets--a role for which they are considered desirable, due to their relatively inoffensive nature and small size in comparison with other bears.
The IUCN reclassified the Sun Bear from "data deficient" to "vulnerable" status in 2007

Leafy Sea Dragon

The leafy sea dragon, Phycodurus eques, is a marine fish related to the seahorse. It is the only member of the genus Phycodurus. These creatures are found around southern and western Australia. Their name comes from their appearance, with long leaf-like protrusions coming from all over the body. These protrusions are not used for propulsion; they serve only as camouflage. The leafy sea dragon propels itself by means of a pectoral fin on the ridge of its neck and a dorsal fin on its back closer to the tail end. These small fins are almost completely transparent and difficult to see as they undulate minutely to move the creature sedately through the water, completing the illusion of floating seaweed.

Much like the seahorse, the leafy sea dragon's name is derived from its resemblance to another creature (in this case, a mythical sea monster from Irish legends, called the "Cler"). While not large by sea monster standards, they are slightly larger than sea horses, growing to at about 30cm . They feed on plankton and small crustaceans.
The lobes of skin that grow on the Leafy Sea Dragon give it the appearance of seaweed, allowing it to camouflage with its surroundings. Its leafy appearance also allows it to appear to move through the water like a piece of floating seaweed. The Leafy Sea Dragon can also change color to blend in, but this ability relies on the sea dragon's diet, age, location, and stress levels.
The Leafy Sea Dragon has a long, pipe-like snout that it uses to feed. It primarily eats crustaceans including plankton and mysids, but its diet also includes shrimp and other small fish. It catches its prey using its camouflage ability. Leafy sea dragons oddly enough do not have teeth, which is rare amongst animals that eat small fish and shrimp.
The Leafy Sea Dragon is related to the pipefish and belongs to the family Syngnathidae, along with the seahorse. The Leafy Sea Dragon differs from the seahorse in its appearance, form of locomotion, and the Leafy Sea Dragon's inability to coil or grasp things with its tail. A related species is the weedy sea dragon, which is multi-coloured and grows weed-like fins and can be much smaller than the leafy sea dragon. In the November 2006 issue of National Geographic magazine, marine biologist Greg Rouse is reported as investigating the DNA variation of the two sea dragon species across their ranges.

The leafy sea dragon is the official marine emblem of the state of South Australia. A biennial Leafy Sea Dragon Festival is held by the District Council of Yankalilla, South Australia. It is a festival of the environment, arts and culture of the southern Fleurieu Peninsula, with a theme of celebrating the leafy sea dragon. The inaugural festival in 2005 attracted over 7000 participants and visitors.

As with seahorses, the male Leafy Sea Dragon cares for the eggs. Females deposit eggs on the tail of the male where they grow to maturity. The female produces up to 250 bright pink eggs, then passes them on to the male's tail via a long tube. The eggs then attach themselves to a brood patch, which supplies them with oxygen. It takes a total of nine weeks for the eggs to begin to hatch, depending on water conditions. The eggs turn a ripe purple or orange over this period. After this period, the male pumps its tail until the infants emerge, a process which takes place over 24-48 hours. The male aids in the babies hatching by shaking his tail, and rubbing it against the seaweed and rocks. Once born, the infant sea dragon is completely independent from its parents, eating small zooplankton until large enough to hunt mysids. Leafy sea dragons take about 28 months to reach sexual maturity.

The Leafy Sea Dragon uses the fins along the side of its head to allow it to steer and turn. However, its outer skin is solid, limiting its mobility.
Individual Leafy Sea Dragons have been observed remaining in one location for extended periods of time (up to 68 hours) but will sometimes move for extended periods. Tracking of one individual indicated it moved at up to 150m per hour.

Leafy Sea Dragons are subject to many threats, both natural and man-made. They are caught by collectors, and used in alternative medicine. They are vulnerable when first born, and are slow swimmers, reducing their chance of escape from a predator or other threat. They are also very fragile and thus are tossed around easily in storms, and can be ruptured by changes in water pressure. They have become endangered through pollution and industrial runoff as well as collection by fascinated divers who are entranced by their unique appearance. In response to these dangers they have been officially protected by the Australian government.

The Leafy Sea Dragon is found only in the waters of Australia from Kangaroo Island on the Southern shoreline to Jurien Bay on the Western shoreline. It was once thought to be very limited in its range; however, further research has discovered that the sea dragon will actually travel several hundreds of meters from its habitat, returning to the same spot using its strong sense of direction. Leafy Sea Dragons are found around clumps of sand in waters up to 50 meters deep, hiding among rocks and sea grass.

Sea dragons are protected by Australian law. Obtaining them is often an expensive and difficult process as they must be from captive bred stock, and exporters must prove their broodstock were caught before collecting restrictions went into effect, or that they had the correct licenses to collect them. To date, no successful, closed cycle, captive-breeding program has occurred (ie getting a generation of captive-raised sea dragons to breed). Sea dragons have a specific level of protection under fisheries legislation federally and in most Australian states where they occur, such that it is illegal to take or export them without a permit

They are very fragile and unstable outside their natural habitats. Success keeping them has been largely in the public aquarium sector, due to funding and knowledge that would not be available to the average aquarium enthusiast.
