SCIENTISTS SURPRISED BY SEA SLUGS THAT SEVER THEIR OWN HEADS AND REGROW BRAND-NEW BODIES

Commonly, there are some animals that can loose and regenerate a tail or limb, unlike these animals, scientist have discovered two species of sacoglossan sea slug, that can regenerate more better. These specie have the ability to regenerate a whole new body complete with the heart and other internal organs. Really interesting.

This is possible due to the photosynthetic ability of chloroplasts they get from the algae in their diet, this helps the slugs to survive long enough for regeneration, said “the researchers”. The process of regeneration takes about three weeks. The head first separate from the whole body, moves aside and starts to feed on algae within hours, regeneration begins.

These findings in sea slugs represent a new type of autotomy in which animals with complex body plans shed most of their body.
