Distribution

edit

This species was first described from Brittany, France. It has rarely been reported since the original description. Henning Lemche identified it with the common species which feeds on the hydroid Dynamena pumila, predominantly in the intertidal region.[3]

Description

edit

This nudibranch is translucent white with dark red spots on the ceratal tubercles. The back and sides are spattered with red pigment which extends up the inner faces of the rhinophore sheaths.[4] It is illustrated in colour in a more detailed publication by Hesse in 1873.[5]

Ecology

edit

Doto onusta feeds on the hydroid Dynamena pumila, family Sertulariidae.[3]
