About Cuthona phoenix Gosliner, 1981
Cuthona phoenix (also referenced as Tenellia phoenix) is a small translucent aeolid nudibranch. It has swollen cerata, and a central line of its digestive gland is visible through its skin. This species resembles both Tergipes tergipes and Eubranchus rupium, but is intermediate between these two species in the number and arrangement of its cerata. Its oral tentacles and rhinophores are covered with brown pigment. This species was first described from a specimen collected at La Jolla, California, United States. It has been recorded along the California coast from Monterey Bay to Mission Bay in San Diego, and also from Costa Rica.
