Why Animals Keep Self-Amputating

The video explores the concept of autotomy, where animals intentionally shed body parts. Lizards use it to escape predators, while sea slugs decapitate themselves to eliminate parasites and regrow their bodies. Leaf-footed cactus bugs may amputate injured limbs to prevent infection, though they cannot regrow them. Some spiders sacrifice parts of their mating organs to ensure reproductive success. These behaviors highlight the diverse reasons for self-amputation in the animal kingdom, from survival to reproduction.
