Family Symbiidae



Phylum Cycliophora

This bizarre phylum was first discovered in 1993, feeding on the mouthparts of a Norway lobster. Only one species is known and has been labeled the pandora. This small creature (at the largest only 350 um - smaller than a period) has a complex life cycle in which several different sessile and free-swimming stages are known. Pandoras are most noted for their circular mouth, which is surrounded by fine cilia. Indeed, Cycliophora means "carrying a small wheel".

Pandoras have a complete digestive tract. The S-shaped esophagus leads to the stomach cells, after which lie the rectum and anus. Pandoras reproduce both sexually and asexually. Males are much smaller than females and lack a digestive tract. They appear only when the lobster is about to moult, and have the soul purpose of breeding. This is evidenced by their having two penises.
