sloth

Reduction in tooth number is a common character among sloths, with the two genera of extant tree sloths (the three-toed sloth, Bradypus, and the two-toed sloth, Choloepus) possessing a 5/4 dental formula.

The research was part of an ongoing monitoring programme in which males and female two-toed sloths across the study site were located, tagged and genetically tested.

Two-toed sloth (Choloepus hoffmanni) young become independent of their mothers between nine to twelve months of age in captivity (Veselovsky 1966, Meritt 1985, Partridge 1991).

Other new additions include two goldenhead lion tamarins, two two-toed sloths and hundreds of tiny baby seahorses.

Champion sleepers in the animal world are two-toed sloths.

Two-toed sloths tend to be larger, with bigger eyes and longer hair than their three-toed cousins.

And there is a host of unusual creatures such as the critically endangered species of lemurs known as the Alootran Gentle Lemur, and Linnes two-toed sloths, creatures which spend most of their day hanging around up-sidedown.

On this tiny island, just 15 square kilometres, there are nearly 400 types of birds and 100 species of animals, from howler monkeys to two-toed sloths. These animals kept their feet dry when the canal was flooded by fleeing to the higher ground of an island that's be come a modern-day Noah's Ark.
