'''''Symbion''''' is a [[genus]] of [[Commensalism|commensal]] aquatic animals, less than 0.5&nbsp;mm wide, found living attached to the mouthparts of cold-water lobsters. They have sac-like bodies, and three distinctly different forms in different parts of their two-stage life-cycle. They appear so different from other animals that they were assigned their own, new [[phylum]] '''Cycliophora''' shortly after they were discovered in 1995.<ref>{{cite web |url=https://www.newscientist.com/article/dn18834-zoologger-the-most-bizarre-life-story-on-earth/ |title=Zoologger: The most bizarre life story on Earth? |last=Marshall |first=Michael |date=28 April 2010 |website=New Scientist |access-date=19 November 2018 |quote=...&nbsp;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.&nbsp;...}}</ref> This was the first new [[phylum]] of multicelled organism to be discovered since the [[Loricifera]] in 1983.
