Obligate cannibalism

An obligate cannibal is a life form that must feed on members of its own species in order to survive. Usually this is the result of the species not being able to create certain proteins from other food sources and must take it from members of their own species in order to survive.
While a condition to fit the category, not all obligate cannibals are beasts, as the latter are necessarily members of a species that are not all cannibals.
