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.
large relatives of the modern two-toed and three-toed sloths. Ground sloths evolved in South America around 35 million years ago, and migrated into North America, starting around 8 million years ago, with the last species arriving during the Pleistocene. All four species became extinct approximately 10,000 years ago. The reason for their extinction is not currently known.
