10 Animals That Can Literally Bring Themselves Back to Life
4. Sea Cucumbers: The Evisceration Escape Artists

Sea cucumbers, intriguing echinoderms found on ocean floors, have a unique defense mechanism that involves expelling their internal organs when threatened. This process, known as evisceration, allows them to escape predators while leaving behind a decoy. Remarkably, sea cucumbers can regenerate their lost organs within weeks, underscoring their resilience. This ability is facilitated by specialized cells that proliferate and differentiate to replace the ejected tissues. The study of sea cucumber regeneration sheds light on the molecular and cellular processes underlying organ regeneration, offering potential applications in regenerative medicine and organ transplantation.
