Some octopuses have started eating their own limbs and then dying, which scientists originally chalked up to autotomy, a behavior in which an animal will break off a limb for self-protection. The eight-limbed mollusks even have a preference when it comes to which arm they use for eating. Octopuses have six arms and two legs, not eight tentacles as they are sometimes mistakenly called.

Octopuses have the unique ability to regenerate a fully functional arm in about 100 to 130 days.
