Fairly common. When stretched may look more elongate than oval. Lamellate rhinophores with distinctive coloured band. Simple gill arranged in a circle. Both are fully retractable.
General Notes
Hypselodoris maculosa is very similar to Hypselodoris decorata and at one time they were thought to be the same species. The best way to tell them apart is by counting the rings on the rhinophores. Maculosa has two and decorata has three. The body is more pink with purple spots on maculosa, decorata is more cream with red spots.
