Cannibalism in animals

In zoology, cannibalism is where an animal eats its own species. It has been recorded for more than 1500 species.[1] It is quite common with insects, spiders and scorpions. There, the male gets eaten by the female, after having sexual intercourse. Many types of frogs will also eat other frogs of the same species. Even, vetebrates like hedgehogs eat their offspring if stressed.[2][3]
