Having undergone self-amputation or having had a body part voluntarily or reflexively detached.
From 'autotomize' (American spelling) + past participle '-ed'. American English variant of autotomised.
An autotomized sea cucumber is one of nature's wildest sights—it's voluntarily expelled its own internal organs as a defense! These organs regenerate completely, and the defense is so effective that predators often decide the cucumber isn't worth eating.
