Cannibalization
Version 1.0.0 · Updated 2026-07-28
CORE DEFINITION
In zoology, cannibalism, self-devouring, or intraspecific predation refers to the behavior of consuming members of one's own species as food. In the animal kingdom, this is a common ecological interaction, with over 1,500 species recorded exhibiting this behavior. Disease, starvation, and population density can all lead to cannibalism. Cannibalism is more common in the marine world, while higher terrestrial species generally exhibit it less frequently. Cannibalism among mammals (including humans) can cause transmissible spongiform encephalopathies.
