I can't find the name of this sea slug. Could you help me? I thnk it belongs to the Family Chromodorididae?

Dear Fabrice,
Yes this is a chromodorid. It is Hypselodoris nigrostriata, and like other animals of this species from the western Indian Ocean it has much more prominent yellow markings than found in specimens from further east. It also appears to be feeding on, or at least interested in, the grey-blue sponge which seems to cover quite a bit of the substrate, and be partly overgrown by branching coralline algae. The sponge appears to be a dysideid sponge which this species has been reported on before [#9500, #6017 ]

Best wishes,
Bill Rudman
