Dendronotus robilliardi is a species of sea slugs, a dendronotid nudibranch, a shell-less marine gastropod mollusc in the family Dendronotidae.[2]

Taxonomic history

This species was correctly recognised as separate from Dendronotus albus by Robilliard in 1960.[3] However he identified it as D. albus and described the true D. albus as Dendronotus diversicolor.[1]

Distribution

This marine animal can be found in the NE Pacific Ocean from Alaska to California and in the NW Pacific from Russia and Korea.[1]

Description

This species grows to a maximum length of 40 mm. It is distinguished from Dendronotus albus by having more than four pairs of cerata, (typically 5 to 7), whilst D . albus is a bigger animal but has no more than four or five pairs.[3] The body and cerata are translucent white with opaque white and orange-yellow tips to the cerata, although in some cases the orange-yellow is absent.[4]

Diet

This species feeds preferentially on the hydroid Thuiaria argentea in the family Sertulariidae.[3] Dendronotus albus is said to prefer Abietinaria greenei, Hydrallmania distans and Abietinaria amphora.[3]
