Urticina crassicornis: Painted Anemone–The Race Rocks Taxonomy


Ryan Murphy photo of this species.

In this video, the soft pink coral Gersemia rubiformis is highlighted. It grows at 7-10 meters over a 3 square meter area off peg #3. Other organisms shown in association in the same area are: Anemone- (both Tealia and Epiactis), hydroids, sponges and colonial ascidians .
Urticina crassicornis has previously been called ” Tealia” anemone. They are one of the most abundant large anemone at Race Rocks in the subtidal area. They use their nematocysts expelled from their stout tentacles for the immobilization of small fish, crustaceans such as krill and anything organic that drifts their way.Pieces of dead fish have been seen clinging to the tentacles. They are believed to live a very long time, as long as they are in an area well supplied with food by the current.
