Concerning message #22015:

Dear Bill,

Following David's message, attached is another Goniodoridella species from Heron Island. The animals were all found under dead coral slabs at the reef crest at low tide and ranged from 2.5 to 3 mm in size. Their general body colour was white except for the tip of the tail which was pale yellow. The extra branchial papillae are also white with a faint yellow tip and the rhinophores are mainly brown.

Locality: Heron Island, Intertidal, Queensland, Pacific, December 1995, Intertidal. Length: 3 mm. Photographer: Julie Marshall.

Best wishes,
Julie Marshall

Thanks Julie,

I should have remembered this animal you reported in your Great Barrier Reef book. Like David & Gary's species the gills in yours appear to be very rudimentary. I have included a close-up to show the spiculate conical tubercules on the body
