Hypselodoris bennetti (Angas, 1864)
Occasionally extremely common throughout the Solitary Islands Marine Park (SIMP). Only known from the east coast of Australia, most records in NSW.
Found in shallow to deep rocky reef.
This attractive dorid is often found in pairs, is diurnally active and grows to 60mm, although is often smaller in the SIMP. Its food sponge is Psammocinia sp. This sponge is often overgrown with algae and not easily recognisable. Mating pair pictured in the top photograph. Similar Goniobranchus hunterae has pale gills and rhinophores.
