Deep dives
The Prevalence of Cannibalism in the Animal Kingdom
Cannibalism is widely practiced throughout the animal kingdom, often serving as a natural ecological interaction rather than an aberrant behavior. Many species exhibiting predatory traits also demonstrate cannibalistic tendencies, as consuming members of their own species can yield significant survival advantages. This behavior may provide essential nutrients, help control population density, or eliminate competition for resources. Despite the stigma attached to cannibalism in human culture, its prevalence among non-human animals is frequently overlooked and underreported.
