Japanese researchers recently the incredible ability of a sea slug to basically sever its own head and simply grow a new body, complete with fresh vital organs.

However, autotomy usually involves limbs or tails, appendages that don’t feature vital organs, whish is why a sea slug that can apparently sever its own head and then grow a new body complete with these vital organs has stunned scientists.
