Chromodoris verrieri from Reunion island

April 25, 2006
From: Philibert Bidgrain

Dear Bill,
Reunion Island sea slugs.

In November I observed 3 specimens of this species in a rocky coast at Etang sale les bains (Reunion Island), and since two weeks I found in the same coast two other specimens. All the specimens have the same size (about 10 mm) and exactly the same external pattern. They look like C. albonares, but you say in your forum they are known from northern New South Wales and New Caledonia and reported in Forum from American Samoa. Do you think it's an Indian ocean C albonares??

Locality: etang sale les bains, 1m, Reunion island, Indian ocean, April 2006, intertidal rocky coast. Length: 8 to 10 mm. Photographer: Philibert Bidgrain.

Best Regards
Philibert Bidgrain

Dear Philibert,
The two colour bands around the mantle edge, yellow and red, make me suspect these are Chromodoris verrieri. I realise there is no reddish tinge on the rhinophores but 10 mm is still quite small for that species. Similarly, the relatively large rhinophores may also be a juvenile feature. I m afraid there is no easy way to distinguish adult C. albonares which are small when adult, but have relatively large rhinophores, from juveniles of other chromodorids.

Best wishes,
Bill Rudman
