Taxonomic Group: Cnidarians-Hydrozoans


Corymorpha sp. A. is a very small (2-3 mm height) unidentified hydroid, known only from Point Richmond and Lake Merritt, both in San Francisco Bay, California. It was found in shallow, soft-bottom habitats of variable salinity. We know of no other recent records for this hydrozoan and no impacts have been reported in San Francisco Bay.
