General Characteristics:
The marine flatworm is an unsegmented worm belonging to the phylum platyhelminthes. They are free living marine animals. It has a leaf shaped body with highly ruffle edges. Since they are so thin, they are able to rapidly diffuse oxygen into their bodies. Their digestive system is branched, so nutrients are quickly absorbed. In order to ingest food, the flatworm must push their pharynx out through their mouth and engulf prey much like echinoderms. Their prey usually consists of protozoans, worms and copepods as well as bivalves. Flatworms are hermaphrodites.
Habitat:
The marine flatworm inhabits tropical and subtropical ocean waters.
Importance to Humans:
Some species of marine flatworms can be very brightly colored, making them a good diving attraction for tourists.
