Bobbit Worm
Eunice aphroditois
The bobbit is my favorite worm. It can grow up to a meter, has a stunning purple iridescence, five antennae to sense passing fish and a scissor-like mouth to split prey in half. Most of the body is covered in sand, just enough is exposed to ambush surprised fish. This worm is quite rare, shy, and mysterious.
