Leafy seadragon
Named after the dragons of Chinese mythology, Leafy seadragons (Phycodurus eques) resemble a piece of drifting seaweed as they float in the seaweed-filled water. The Leafy seadragon, with green, orange and gold hues along its body, is covered with leaf-like appendages, making it remarkably camouflaged. Only the fluttering of tiny fins or the moving of an independently swiveling eye, reveals its presence.
Like the seahorse, the male seadragon carries as many as 150-200 eggs. After being deposited by the female, the eggs are carried in the honeycomb-shaped area (known as the brood patch) under the male's tail for approximately eight weeks. Seadragons have no teeth or stomach and feed exclusively on mysidopsis shrimp. Known as "Australian seahorses" in Australia, they are found in calm, cold water that is approximately 50-54° F (10-12° C). Leafy seadragons have been protected by the South Australian government since 1982.
Komondor Dog
Females are 27 inches (69cm) at the withers. Male Komondorok are a minimum of 28 inches at the withers, but many are over 30 inches tall, making this one of the larger common breeds of dog. The body is not overly coarse or heavy, however, and people unfamiliar with the breed are often surprised by how quick and agile the dogs are.
Its long, thick, strikingly corded white coat (the heaviest amount of fur in the canine world) resembles dreadlocks or a mop. The puppy coat is soft and fluffy. However, the coat is wavy and tends to curl as the puppy matures. A fully mature coat is formed naturally from the soft undercoat and the coarser outer coat combining to form tassels, or cords. Some help is needed in separating the cords so the dog does not turn into one large matted mess. The length of the cords increases with time as the coat grows. Shedding is very minimal with this breed, contrary to what one might think (once cords are fully formed). The only substantial shedding occurs as a puppy before the dreadlocks fully form. The Komondor is born with only a white coat, unlike the similar-looking Puli, which is usually white, black or sometimes grayish. However, a working Komondor's coat may be discolored by the elements, and may appear off-white if not washed regularly.
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 wool, which may be removed by shearing 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, Finnish, to name a few.
Emperor Tamarin
The Emperor Tamarin (Saguinus imperator) is a tamarin allegedly named for its similarity with the German emperor Wilhelm II. The name was first intended as a joke, but has become the official scientific name.
This tamarin 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, plus a 35 cm long tail. It weighs approximately 300 to 400 g.
This primate inhabits tropical rain forests, living deep in the forest and also in open tree-covered areas. It is a diurnal animal, spending the majority of its days in the trees with quick, safe movements and broad jumps among the limbs.
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 monkey mostly feed on fruits, but also nuts, seeds, and insects.
Hagfish
Hagfish are marine craniates of the class Myxini, also known as Hyperotreti. 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 commonly defined 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.
Hagfish are long, vermiform and can exude copious quantities of a sticky slime or mucus (from which the typical species Myxine glutinosa was named). When captured and held by the tail, they escape by secreting the fibrous slime, which turns into a thick and sticky gel when combined with water, and then cleaning off by tying themselves in an overhand knot which works its way from the head to the tail of the animal, scraping off the slime as it goes. Some authorities conjecture that this singular behavior may assist them in extricating themselves from the jaws of predatory fish. However, the "sliming" also seems to act as a distraction to predators, and free-swimming hagfish are seen to "slime" when agitated and will later clear the mucus off by way of the same travelling-knot behavior.
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.
It lives in wet lowland areas and eats small invertebrates, aquatic insects, worms and molluscs. It is a good swimmer and can forage along the bottoms of streams and ponds. Like other moles, this animal digs shallow surface tunnels for foraging; often, these tunnels exit underwater. It is active day and night and remains active in winter, when it has been observed tunnelling through the snow and swimming in ice-covered streams. Little is known about the social behavior of the species, but it is suspected that it is colonial.
The Star-nosed Mole is covered in thick blackish brown water-repellent fur and has large scaled feet and a long thick tail, which appears to function as a fat storage reserve for the spring breeding season. Adults are 15 to 20 cm in length, weigh about 55 g, and have 44 teeth. The mole's most distinctive feature is a circle of 22 mobile, pink, fleshy tentacles at the end of the snout. These are used to identify food by touch, such as worms, insects and crustaceans.
Axolotl
The Axolotl (or ajolote) (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. 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, Australia, Japan (where they are 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 is widespread in much of North America which also occasionally become neotenic, nor with mudpuppies (Necturus spp.), fully aquatic salamanders which are unrelated to the axolotl but which bear a superficial resemblance.
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 unique 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.
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 an endangered species); a second species (Daubentonia robusta) was exterminated over the last few centuries.
Alpaca
The Alpaca (Vicugna pacos) is a domesticated species of South American camelid developed from the wild alpacas. It resembles a sheep in appearance, but is larger and has a long erect neck as well as coming in many colors, whereas sheep are generally bred to be white and black.
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 3500 to 5000 meters above sea-level, throughout the year.
Alpacas are considerably smaller than llamas, and unlike them are not used as beasts of burden but are valued only for their fiber. Alpacas only have fleece fibers, not woolen fibers, used for making knitted and woven items much as sheeps wool is. These items include blankets, sweaters, hats, gloves, scarves, a wide variety of textiles and ponchos in South America, and sweaters, socks and coats 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 22 as classified in America.
Tarsier
Tarsiers are prosimian primates of the genus Tarsius, a monotypic genus in the family Tarsiidae, which is itself the lone extant family within the infraorder Tarsiiformes. The phylogenetic position of extant tarsiers within the order Primates has been debated for much of the past century, and tarsiers have alternately been classified with strepsirrhine primates in the suborder Prosimii, or as the sister group to the simians (=Anthropoidea) in the infraorder Haplorrhini. Analysis of SINE insertions, a type of macromutation to the DNA, is argued to offer very persuasive evidence for the monophyly of Haplorrhini, where other lines of evidence, such as DNA sequence data, had remained ambiguous. Thus, some systematists argue that the debate is conclusively settled in favor of a monophyletic Haplorrhini.
Tarsiers have enormous eyes and long feet. Their feet have extremely elongated tarsus bones, which is how they got their name. They are primarily insectivorous, and catch insects by jumping at them. They are also known to prey on birds and snakes. As they jump from tree to tree, tarsiers can catch even birds in motion.[citation needed] Gestation takes about six months, and tarsiers give birth to single offspring. All tarsier species are nocturnal in their habits, but like many nocturnal organisms some individuals may show more or less activity during the daytime. Unlike many nocturnal animals, however, tarsiers lack a light-reflecting area (tapetum lucidum) of the eye. They also have a fovea, atypical for nocturnal animals.
Dumbo Octopus
The octopuses of the genus Grimpoteuthis are sometimes nicknamed "Dumbo octopuses" from the ear-like fins protruding from the top of their "heads" (actually bodies), resembling the ears of Walt Disney's flying elephant. They are benthic creatures, living at extreme depths, and are some of the rarest of the Octopoda species.
Frill-necked Lizard
The Frill-necked Lizard, or Frilled Lizard also known as the Frilled Dragon, (Chlamydosaurus kingii) is so called because of the large ruff of skin which usually lies folded back against its head and neck. The neck frill is supported by long spines of cartilage, and when the lizard is frightened, it gapes its mouth showing a bright pink or yellow lining, and the frill flares out, displaying bright orange and red scales. The frill may also aid in thermoregulation.
They may grow up to one metre in total length. They often walk quadrupedally when on the ground. When frightened they begin to run on all-fours and then accelerate onto the hind-legs. In Australia, the frill-necked lizard is also known as the "bicycle lizard" because of this behaviour. Males are significantly larger than females both as juveniles and when mature. The frill of the Australian frilled dragon is used to frighten off potential predators — as well as hissing and lunging. If this fails to ward off the threat, the lizard flees bipedally to a nearby tree where it climbs to the top and relies on camouflage to keep it hidden.
Narwhal
The Narwhal (Monodon monoceros) is an Arctic species of cetacean. It is a creature rarely found south of latitude 70°N. It is one of two species of white whale in the Monodontidae family (the other is the beluga whale). It is possibly also related to the Irrawaddy dolphin.
The English name narwhal is derived from the Dutch name narwal which in turn comes from the Danish narhval which is based on the Old Norse word nar, meaning "corpse." This is a reference to the animal's colour. The narwhal is also commonly known as the Moon Whale.
In some parts of the world, the Narwhal is colloquially referred to as a "reamfish."
Pygmy Marmoset
The Pygmy Marmoset (Callithrix (Cebuella) pygmaea) is a monkey native to the rainforest canopies of western Brazil, southeastern Colombia, eastern Ecuador, and eastern Peru. It is one of the smallest primates, with its body length ranging from 14-16 cm (excluding the 15-20 cm tail) and the smallest monkey. Males weigh around 140 g (5 ounces), and females only 120 g (4.2 ounces).
TDespite its name, the Pygmy Marmoset is somewhat different from the typical marmosets classified in genus Callithrix. As such, it is accorded its own subgenus, which was formerly recognized as its own genus, Cebuella.
TThe Pygmy Marmoset has a tawny coat, and a ringed tail that can be as long as its body. Their claws are specially adapted for climbing trees, a trait unique to the species. They are omnivorous, feeding on fruit, leaves, insects, and sometimes even small reptiles. Much of their diet, however, comes from tapping trees for sap. Up to two-thirds of their time is spent gouging tree bark to reach the gummy sap. The Pygmy Marmoset has specialized incisors for gouging holes in bark. Unfortunately, because of its small size, and its swift movements, it is very hard to observe in the wild.
TIn captivity, the Pygmy Marmoset can live up to 11 years.
Blobfish
The blobfish (Psychrolutes marcidus) is a fish that inhabits the deep waters off the coasts of Australia and Tasmania. Due to the inaccessibility of its habitat, it is rarely seen by humans.
Blobfish are found at depths where the pressure is several dozens of times higher than at sea level, which would likely make gas bladders inefficient. To remain buoyant, the flesh of the blobfish is primarily a gelatinous mass with a density slightly less than water; this allows the fish to float above the sea floor without expending energy on swimming. The relative lack of muscle is not a disadvantage as it primarily swallows edible matter that floats by in front it.
Yeti Crab
Kiwa hirsuta is a crustacean discovered in 2005 in the South Pacific Ocean. This decapod, which is approximately 15 cm (6 inches) long, is notable for the quantity of silky blond setae (resembling fur) covering its pereiopods (thoracic legs, including claws). Its discoverers dubbed it the "yeti lobster" or "yeti crab".
K. hirsuta was discovered in March 2005 by a group organised by Robert Vrijenhoek of the Monterey Bay Aquarium Research Institute in Monterey, California, using the submarine DSV Alvin, operating from RV Atlantis. The discovery was announced on the 7th of March, 2006. It was found 1,500 km (900 miles) south of Easter Island in the South Pacific, at a depth of 2,200 m (7,200 feet), living on hydrothermal vents along the Pacific-Antarctic Ridge. Based on both morphology and molecular data, the species was deemed to form a new genus and family (Kiwaidae). The animal has strongly reduced eyes that lack pigment, and is thought to be blind.
The 'hairy' pincers contain filamentous bacteria, which the creature may use to detoxify poisonous minerals from the water emitted by the hydrothermal vents where it lives. Alternatively, it may feed on the bacteria, although it is thought to be a general carnivore. Its diet also consists of green algae and small shrimp.
