Stenothoe valida
Taxonomic Group: Crustaceans-Amphipods


Stenothoe valida is a small marine amphipod. It was described from Rio de Janeiro, Brazil, but populations are known from warm-water ports around the world, making its native range difficult to determine. Relatively recent records from Hawaii and California are believed to be introductions. Records from the East Coast of North America are considered cryptogenic (i.e. of unknown origin) because it closely resembles a native amphipod species and could have been easily overlooked historically. It is commonly associated with hydroids, algae, and other fouling organisms, on docks, floats, buoys, and ships’ hulls.
