White bear is a mammal that lives in the icy poles or areas. They are warmed by a thick layer of fat under your skin color is black which also helps to attract the sun and thus be even more sheltered from the cold.

The male specimen usually weighs about 500kg although some have been known some who have passed the ton. The females weigh on average half the males of their species.

The polar bears were about to enter the list of endangered animals but thanks to the prohibition of hunting of the same stopped the decline of the species.

Finally add a curiosity is that polar bears are white or use your hands and feet left to perform their tasks, therefore, are considered left-handed animals.

This is perhaps the most peculiar member of the order of primates. His appearance and nocturnal habits around him an aura of mystery and the presence of elongated middle finger adds a touch extravagant. Therefore, it is not surprising that farmers in Madagascar will consider a bad omen and if one is found near their village, they kill or abandon the latter.

Despite their much particularized characteristics, the Aye-aye is almost certainly a member of the lemurs and is found only in Madagascar, like all other lemurs. Is a typical species of the rain forest and its natural habitat is the built in coastal forests of the Northeast. However, the destruction of their forest habitat has caused the virtual extinction of so remarkable specimen. Fortunately, we have recently introduced a dozen individuals in the island of Nosy Manage reserves in the Bay of Antonio (northeast of Madagascar), and perhaps this is the only chance of preservation.

Introduced animals seem to have adapted well and perhaps may represent the beginning of a viable colony. Aye-aye is characteristic of staying on top of the vertical trunks and thick branches of trees in tropical rainforests. Consume a mixed diet of insects and plants, but spend a large part of their energies to hunting insects. It is in this activity come into play two of its main features. Unlike other lemurs, Daubentonia has two continuously growing incisors in the upper jaw and the same number at the bottom.

No dogs and has a gap (diatom) between incisors and premolars. This type of rodent teeth combined with the middle finger, long and thin, the search for insect larvae. It seems that the Aye-aye uses its sense of smell and their large ears to locate the larvae moving under the bark of dead branches.

Once this is achieved, using fast and intense incisors to drill a hole and the thin middle finger of one hand to remove the larvae. It does not seem true, as was thought at one time, used the long finger to pierce the bark in search of aquellas.Casi whole animal nocturnal activity focuses on the pursuit and capture of larvae. In the remaining periods eats small amounts of fruit, using incisors peeling or cracking finger fruit and long to make tasty snacks and place then in the mouth between the incisors and the premolars. You can also combine two types of food seeking parasite larvae in the heart of soft fruit.

The only other member of the family of Doubleton Aye-aye is a relatively recent fossil, Daubentonia robustus, larger than the living variety, but like it in every other feature of the skeleton. Most authors make out all the lemurs from a common ancestor isolated on Madagascar about 50 million years, but some of the peculiar features of Dubentonia suggest that this period was longer and the animal comes from an ancestral form separate, isolated in Madagascar when the island was formed.

The “yurumí” has a heavy coat whose color varies from black to white through various shades of gray and lasts a long tail, full of hair up to 40 inches long, which give an aspect of range or flag. ” This species has units that reach 2 meters long, 80 cm which correspond to the tail. The weight of an adult male can reach 40 kilos. its snout is long and narrow, has no teeth and his tongue is long. He is armed with two powerful claws burrowing in the front legs.

• Name

“Yurumí” is the name given in Guarani, but also calls it “tamanduáguazú”, “large anteater”, “anteater flag” (for its attractive tail). Its scientific name is “Myrmecophaga tridactyla (Linnaeus). Belongs to the class of mammals, order and family Vermilingua Myrmecophagidae. This species has, since 1977, a symbol of the Fundación Vida Silvestre Argentina.

• Habitat

From Venezuela and Guyana to some provinces in northern Argentina: the forest of Misiones, Formosa, Chaco and other areas impenetrable, east of Salta, Santiago del Estero northeast and probably north of Corrientes. In all these regions showing search areas covered or open savannah grasslands where there are termites or tacurús, fair-sized structures built by these invertebrates.

• Food

The diet of “yurumí is insectivorous, based mainly on ants and termites, which it extracts with its long sticky tongue. To achieve open gaps in the colonies of these insects, using the long, curved claws on its front legs.

• Their offspring

The gestation period of “yurumí” lasts about 190 days, after which it is born, usually in spring, a small farming weighs 1600 grams. The mother carries on her back for breeding from the first two or three weeks and for over a year.

• For what is at stake

There are three reasons that make us fear for the perpetuation of this species, altering their natural habitat, low reproductive potential and high vulnerability to man. As forests are cut down gradually to give refuge, secretly captures it for sale to zoos and private collectors.
