Mimetridium
Mimetridium is a genus of hydrozoans in the family Corynidae. It is found in the Atlantic Ocean and the Mediterranean Sea.
Common Names
Common names for species within this genus include the "sea gooseberry" and "polyp."
Characteristics
Mimetridium species are small, colonial hydrozoans with a polyp stage and a medusa stage. They are characterized by their bell-shaped medusae, which have a distinctive pattern of tentacles. They have a single ring of tentacles around the edge of the bell, and these tentacles are typically long and thin, often with a cluster of smaller tentacles at their base. The polyp stage of these hydrozoans is attached to a substrate, and it is often found on rocks, algae, and other marine organisms.
Environments
Mimetridium species are typically found in shallow coastal waters, often in rocky intertidal zones. They are also known to occur in deeper waters, but they are generally more abundant in shallower habitats.
