Rostanga arbutus | |
This species was described from New South Wales, Australia. It was thought to be widely distributed, but this was due to confusion with other species. [2]
This dorid nudibranch is bright orange to reddish-orange in colour, and the dorsum is covered with caryophyllidia. It is very similar to other species of Rostanga, but it is distinguished by a series of white markings, the mantle glands, which are just inside the mantle edge.[2][3]
This species is found mostly in the intertidal zone on the red sponge, Ophlitaspongia aceratoobtusa (family Microcionidae) on which it presumably feeds.[2] Most other species of Rostanga also feed on sponges of the family Microcionidae.
