Clava multicornis
Taxonomic Group: Cnidarians-Hydrozoans
Common name: CLUB HYDROID

Overview:

Clava multicornis is a sessile hydrozoan, which lacks a planktonic medusa stage. It is native to the North Atlantic, ranging from Long Island to Labrador, Iceland, the White Sea, and the Bay of Biscay. It was introduced to San Francisco Bay, California, but has not been collected there in more than 50 years. However, in 2013, extensive established colonies were found on floating docks in Coos Bay, Oregon. It can settle on a variety of substrates, including seaweeds, mollusk shells, rocks, pilings, and buoys. No impacts have been reported for this species.
