The Pen-tailed anteater is a type of giant anteater-like species of anteater that has a really sharp pen-like tail. It uses its tail to stab insects with it. Its tail has a paralyzing sting that kills insects if stung long enough, but it is harmless to larger species, including humans. Its tail drops the insect to the ground before eating it. It is very rarely agressive to humans. It is an insectivore. It lives in the rainforests of South America.
