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.

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.

Tapirs

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, horses and rhinoceroses.

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.

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.

Sloth

Sloths are medium-sized mammals that live in Central and South America belonging to the families Megalonychidae and Bradypodidae, part of the order Pilosa. Most scientists call these two families the Folivora suborder, while some call it Phyllophaga.
Sloths are omnivores. They may eat insects, small lizards and carrion, but their diet consists mostly of buds, tender shoots, and leaves.
Sloths 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 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 as long as 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 degrees Celsius or 86 to 93 degrees Fahrenheit), and still lower temperatures when resting. Sloths mainly live in Cecropia trees.

Red Panda

The Red Panda, Ailurus fulgens ("shining cat," from a Latinized form of the Greek, ailouros, "cat," and the participial form of the Latin fulgere, "to shine") is a mostly herbivorous mammal, slightly larger than a domestic cat (55 cm long). The Red Panda has semi-retractile claws and, like the Giant Panda, has a "false thumb" which is really an extension of the wrist bone. Thick fur on the soles of the feet offers protection from cold and hides scent glands. The Red Panda is native to the Himalayas in Nepal and southern China. The word panda is derived from Nepalese word "ponya" which means bamboo and plants eating animals in Nepal.
