Cool worm, right? Well, it’s actually an amphibian. Meet Microcaecilia dermatophaga, a species belonging to a group of limbless amphibians called caecilians. This critter can be found in parts of northeastern South America, where it inhabits sandy loam on the forest floor. As an adult, it munches on termites, ants, and earthworms. And as a juvenile? It feeds on its mother’s skin! Don’t worry: As her children begin to feed on live prey, the mother eventually regains the mass she lost to her hungry offspring.
