Symbion
From Wikipedia, the free encyclopedia.
Symbion is a genus of peculiar animals, with a single species, S. pandora. It was discovered in 1995 by Kristensen on the mouthparts of the Norwegian lobster Nephrops. Symbion does not appear to have any especially close relatives, and so was given its own phylum, called Cycliophora. It may be related to the Ectoprocta and Entoprocta.
