cannibalism

In zoology, the eating of any animal by another member of the same species.

Certain ants regularly consume injured immatures and, when food is scarce, eat healthy immatures; this practice allows the adults to survive the food shortage and live to breed again. Male lions taking over a pride may kill and eat the existing young. After losing her cubs the mother will become impregnated by the new dominant male, thereby ensuring his genetic contribution. Aquarium guppies sometimes regulate their population size by eating most of their young.

   from the prehistoric religion article
In finds belonging to the Paleolithic Period, pieces of human bodies as well as the bones of other animals are found scattered throughout the archaeological layers and are sometimes broken or charred. This is often taken as evidence for cannibalism, but other interpretations are just as likely (e.g., the action of carrion-eating animals [such as hyenas] turning up the ...

   from the termite article
The Macrotermitinae (family Termitidae) cultivate symbiotic fungi (Termitomyces). The termites construct spongelike “fungus gardens,” or combs, possibly of fecal matter rich in the carbohydrate lignin. The fungi grow on the combs, and the termites consume both fungi and combs. The fungi break down the fecal matter used to construct the combs into substances that can be ...

The word is also used in a zoological sense to refer to the eating of any animal species by ...

Jack climbs the stalk, spies a giant, and steals the giant's wealth; in a chase down the ...

Aztec tribes were divided into families and clans. Each clan had its own elected officials and sent representatives to the council of the tribe.

Major credit for the discovery and charting of the islands goes to another Englishman, William Bligh, who navigated the islands after being set adrift in a small boat by the mutinous ...
