Doriopsis granulosa from eastern Australia

March 7, 2003
From: Bill Rudman

Rachel Przeslawski's message has shamed me into preparing some information on Doriopsis pecten and D. granulosa. I note that I promised to do this 3 years ago! I am therefore posting simultaneously, a number of messages showing colour range, food sponge and gill shape of both species. Any other information, including egg ribbons, would be very welcome.

These specimens of Doriopsis granulosa are from northern New South Wales. The dorsum was yellow, with low rounded tubercles. These tubercles had scattered brownish specks, especially around the edge, which gave them a brownish outline.

Photo: Arrawarra Headland, Coffs Hbr, NSW, Australia. Upper intertidal under rocks, on sponge which ranged in colour from yellow to orange. 16 Mar 1988. AM C155788. A number of specimens were found, ranging in length from 20-28mm. Photos: Bill Rudman.

Best wishes,
Bill Rudman
