Some people have a geographic tongue, which looks like a mixture of red and white spots (and sometimes like continents on a world map, hence the name). And these people will likely have it for life. You have areas on your tongue where some taste buds have been worn down, says Flohr.
There are two types of sloth. They look quite different and are defined by how many digits they have. Two-toed, Choloepus sloths actually have three toes, but only two fingers and look like a cross between a Wookiee and a pig. There are two species of two-toed sloth and neither is considered endangered, although their jungle homes are being chopped down at an alarming rate. This blissed-out Bradypus is Buttercup, the Queen of Slothville. Threeâtoed Bradypus sloths, have three fingers and three toes, mullet haircuts and Mona Lisa smiles.
Sloths are arboreal mammals noted for slowness of movement and for spending most of their lives hanging upside down in the trees of the tropical rainforests of South America and Central America. The six species are in two families: two-toed sloths and three-toed sloths. In spite of this traditional naming, all sloths actually have three toes. The two-toed sloths have two digits, or fingers, on each forelimb. The sloth is so named because of its very low metabolism and deliberate movements, sloth being related to the word slow. This is an evolutionary adaptation to their low-energy diet of leaves, and to avoid detection by predatory hawks and cats who hunt by sight. Sloths are almost helpless on the ground, but are able to swim.
