Umagillidae
Umagillidae is a family of flatworms belonging to the order Rhabdocoela.
Description
Umagillidae is the most species-rich taxon of symbiotic non-neodermatan flatworms. Umagillids are common endosymbionts of echinoderms, with few species also living inside sipunculids. They demonstrate a wide variety of feeding behaviors, ranging from endozoic predation of symbiotic protozoans to full endoparasitic feeding on its host's tissues. Most species, including species of Seritia and Wahlia are intestinal, while species of Anoplodium are confined to the coelomic regions of its host.Genera
