Friends often can't tell whether Sid in the Ice Age is a sloth (lan) or a tree otter (ta), and I can't tell at the beginning that I have heard such a story:
There was a teacher who, when explaining sloths in class, said that they were otters, and they took it for granted: How can there be a name for sloths? It's not a correct animal name at first glance!
So I was very emotional, not knowing is not terrible, the terrible thing is not to know that you do not know.
In fact, only sloths do not have the animal of the otter.
Sloth is a common name for the suborder Lycaenidae (scientific name: Folivora) of the mammalian order Phiphi, mammals, with 2 families, 2 genera and 6 species. The shape is slightly monkey-like, the movement is slow, and the claws are often hung upside down on the branches for several hours without moving, so it is called sloth. Sloth is the only wild animal with plants on its body, and although it has feet, it cannot walk, and it drags its body forward on its forelimbs.
It is found in South America. The hair is fluffy and thick; the head is short and round, the ears are small and hidden in the hair; the tail is short; the forelimbs have 3 fingers, and the hind limbs have 3 toes, all of which have sharp claws that can be bent, and the forelimbs are longer than the hind limbs; the upper jaw has 5 pairs of teeth, and the lower jaw has 4 pairs of teeth, a total of 18; the stomach fraction chamber; the cervical vertebrae 9 segments, which is the most popular among mammals; the whole body coat color is gray-brown because the hair on the body is attached to algae, and the appearance is green.
