@.extremenature: The Deep-Sea Animal That Throws Its Own Organs at Predators — Then Grows Them Back (Sea Pig) When threatened, it ejects its own internal organs through its body wall. Then grows them back in weeks. The sea pig walks the abyssal plain on hydraulically inflated tube feet, extracting nutrition from mud too dilute for almost any other organism. It detects the chemical signature of a sinking carcass from kilometres away — and hundreds converge on the same source simultaneously. The abyssal plain looks empty. It isn't. It is being processed — continuously — by something that looks like it shouldn't be alive. Did you know some animals expel their own organs as a defence mechanism — and simply regenerate them?
