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.
Adult frill-necked lizards 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 scare 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.
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. Although the group was once more widespread, all the species living today are found in the islands of South East Asia.
Tarsiers are small animals with enormous eyes and very long hind limbs. Their feet have extremely elongated tarsus bones, from which the animals get their name. The head and body range from 10 to 15 cm in length, but the hind limbs are about twice this long (including the feet), and they also have a slender tail from 20 to 25 cm long. Their fingers are also elongated, with the third finger being about the same length as the upper arm. Most of the digits have nails, but the second and third toes of the hind feet bear claws instead, which are used for grooming. Tarsiers have very soft, velvety fur, which is generally buff, beige, or ochre in color.
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, appears to have become extinct at some point within the last 1000 years.

The Aye-aye is the world's largest nocturnal primate, 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 houses 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 thin, and appear to be in a curved position somewhat similar to that of a fairy-tale witch when the muscles are relaxed. 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.

Proboscis Monkey
The Proboscis Monkey (Nasalis larvatus), also known as the Monyet Belanda, the Bangkatan or simply the Long-nosed Monkey. The Proboscis Monkey is a reddish-brown arboreal Old World monkey. It is the only species in monotypic genus Nasalis.
A distinctive trait of this monkey is the male's large protruding nose from which it takes its name. The nose is thought to be used in mating and is unique to the males of the species, reaching up to 7 inches in length. Besides attracting mates, the nose serves as a resonating chamber and works by amplifying their warning calls. When the animal becomes agitated it's nose swells with blood, making warning calls louder and more intense.
Males are much larger than females, reaching 72 cm (28 inches) in length, with an up to 75 cm tail, and weighing up to 24 kg (53 pounds). Females are up to 60 cm long, weighing up to 12 kg (26 lb). This large sexual dimorphic difference is greater than in any other primate.
The Proboscis Monkey also has a large belly, as a result of its diet. Its digestive system is divided into compartments, with bacteria that digest cellulose and neutralize toxins from certain leaves. This lets the monkey eat leaves and remain in the forest canopy. The contents of their stomach weigh about a quarter of their whole body. A side-effect of this unique digestive system is that it is unable to digest ripe fruit, unlike most other simians. The diet consists mainly of seeds, leaves mangrove shoots and unripened fruit.

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 (under the spelling Axlotl), Australia, Japan (where they are sold under the name Wooper Rooper (????????, Upa Rupa)), and other countries.
Axolotls should not be confused with waterdogs , the larval stage of the closely related Tiger Salamanders (Ambystoma tigrinum and Ambystoma mavortium), 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.

A sexually-mature adult axolotl, at age 18-24 months, ranges in length from 15-45 centimetres (6-18 in), although a size close to 23 centimetres (9 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 cloacas 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 mutants 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 Pichiciago is the smallest species of armadillo (mammals of the family Dasypodidae , mostly known for having a bony armor shell). It is approximately 90-115 mm (3˝-4˝<http://en.wikipedia.org/wiki/Inch>) 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.

Uakari
Uakari is the common name for the New World monkeys of the genus Cacajao. The common name is believed to come from the indigenous term for "Dutchmen"; their red faces apparently reminded the locals of sun-burned European. Cacajao is also believed to be an indigenous name, of unknown meaning now, as the tribe and language is extinct.
The uakaris are unusual among New World monkeys in that the tail length (15-18 cm) is substantially less than their head and body length (40-45 cm). Their bodies are covered with long, loose hair but their heads are bald. They have almost no subcutaneous fat, so their bald faces appear almost skull like. Like their closest relatives the saki monkeys, they have projecting lower incisors.
The three species of uakari currently recognised are both found in the upper Amazon Basin. The Black-headed Uakari is found north of the river, between the Branco River and the Japurá River. The Bald Uakari is found south of the Amazon, on the other side of the Japurá.
Uakaris are typically lethargic and silent in zoo conditions, but in the wild they are agile and active, capable of leaps of over 6 metres. They have been observed both in small groups and in larger troops of up to 100. When travelling through the forest they move in the lower branches of the trees, though when foraging they also go up to the canopy. They eat fruit, nuts, buds and leaves.

Henry Walter Bates, the nineteenth century zoologist, recorded that the Native Americans captured uakaris alive by using blowpipe darts or arrows tipped with diluted curare; once captured the animals were revived by putting a pinch of salt in their mouths. Those animals that survived were kept as pets.
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 Star-nosed Mole lives in wet lowland areas and eats small invertebrates, aquatic insects, worms and mollusks. 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.
The Star-nosed Mole mates in late winter or early spring, and the female has one litter of typically 4 or 5 young in late spring or early summer.
Predators include the Red-tailed Hawk, Great Horned Owl, various skunks and mustelids, and even large fish.

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 of it. It is often caught by bottom trawling with nets.
