GENERAL CHARACTERISTICS: Typically red or orange-pink, occasionally purple, yellow, buff, brown or nearly white.
Corallimorphs are not true anemones. Tentacles end in knobs (club-tipped tentacles) and are not fully retractile, usually being white.

DISTRIBUTION/HABITAT: British Columbia, Canada to Baja California, Mexico. Habitat: Colonies abundant from the low rocky intertidal to 30 m (98 feet).


DIET IN THE WILD: C. californica captures prey by extruding mesenterial filaments onto its prey which are used for digestion and absorption of food in the coelenteron. If the prey is too large to take into the coelenteron, the mesenterial filaments are used to digest it externally. They are carnivores consuming  copepods, crustacean larvae and other zooplankton.

REPRODUCTION: Asexual by fission and budding resulting in a dense cluster of clones

REMARKS: The presence of aggregations of C. californica increase the density of rock oysters and mussels by protecting them from predatory sea stars.
