Though starfish are well understood to utilize their regenerative capabilities to regrow arms eaten or damaged by predators, they are also capable of regenerating arms they have intentionally shed through a process known as autotomy. Researchers propose that autotomy mediated regeneration may play a role in predator evasion as well as both sexual and asexual reproduction. Autotomy is understood to serve a defensive function in starfish.
