12th Annual Smithsonian Magazine Photo Contest Natural World
Worm Serpula vermicularis

I was approaching so slowly to get to close, because this worm (Serpula vermicularis) hides himself very fast into his tube when he feels any danger, like an underwater photograph with his camera, he can feel any small difference of water pressure. This animal extends his tentacles searching for aliment on suspension.
