Rhopalaea crassa

Rhopalaea crassa, is a species of tunicate in the family Diazonidae. Despite, popular online sources, this species is yellow or rarely white. The cobalt blue species often called "Rhopalaea crassa" in error is actually Rhopalaea fusca. A different, undescribed Rhopalaea species with neon-colored networking has also often had this name erroneously attributed to it.
