Crimora lutea? from Tasmania

Dear Bill,

Is this an aberrant Crimora lutea, or a different species? I only found one specimen, at Spring beach, near Triabunna, Tasmania, Australia.

Dear Nerida,
It certainly looks like Crimora lutea to me. I'm not sure what you think is 'aberrant' about it. I know in Willan & Coleman's book their photo is of a specimen with black rhinophore clubs and black edging to the gills but animals I have seen from Tasmania [see photo on right] has yellow rhinophore clubs and whitish gills like your specimen and one from northern New South Wales, [see photo at Top of page], as black rhinophores and yellow gills. Wells & Bryce (1993) illustrate a specimen from Western Australia with black rhinophores and yellowish gills. Baba (1949) does not mention these colour details in his description but the accompanying painting shows yellow rhinophores and gills with a small black line on one gill. Clearly there is some variation.

Photo data: Devonport, Tasmania, Australia, December 1985, 8mm. PHOTO: Bill Rudman.

Best wishes,
Bill Rudman.
