Symbion pandora

A very bizarre creature: http://www.newscientist.com/article/dn18834-zoologger-the-most-bizarre-life-story-on-earth.html

Quote :

In 1995, Peter Funch and Reinhardt Møbjerg Kristensen, both then at the University of Copenhagen, Denmark, discovered an animal so unlike any other that a new phylum – Cycliophora – had to be created just for it.

Symbion pandora, as they called the new creature, is a tiny animal with a complex body and a bizarre life cycle. It still baffles biologists 15 years after it was formally described, and the latest work on its nervous system isn't helping matters.
....
Symbion is a tiny animal about half a millimetre long, shaped like a bulbous tube with a ring of tiny hairs – cilia – at one end.

They live on the hairy mouthparts of Norway lobsters, with tens or even hundreds per lobster. They feed on bits of leftover food and seem to be harmless to their hosts.
