Polyp mimicry in a new species of aeolid nudibranch mollusc

Authors


Abstract

A new species of aeolid mollusc of the genus Cuthona (Tergipedidae) is described from New South Wales, Australia. It feeds on the tubulariid hydroid Zyzzyzus spongicola, and its cerata have developed two circlets of epithelial “tentacles” making the cerata remarkable mimics of the hydroid polyp on which they feed.
