Detailed explanation-1: -Evisceration is a method of autotomy involving the ejection of internal organs used by animals as a defensive strategy. Sea cucumbers (Holothuroidea) eject parts of the gut in order to scare and defend against potential predators such as crabs and fish.
Detailed explanation-2: -Sea cucumbers (a class of echinoderms) exhibit a high capacity for regeneration, such that, following ejection of inner organs in a process called evisceration, the lost organs regenerate. There are two ways by which evisceration occurs in sea cucmber species: from the mouth (anterior) or the anus (posterior).
Detailed explanation-3: -Sea cucumbers can eviscerate themselves, shooting their internal organs through either their head or their butt.
Detailed explanation-4: -Evisceration (pronunciation: /ɪvɪsəˈreɪʃən/) is disembowelment, i.e., the removal of viscera (internal organs, especially those in the abdominal cavity).
Detailed explanation-5: -Evisceration is a form of autotomy practiced by many holothurian echinoderms and involves ejection of the digestive tract and other internal organs (Emson &C Wilkie 1980).
