Atys from Sulawesi
January 26, 2001
From: Lindsay Warren
Dear Bill
I wonder whether you might be able to shed some light on the attached opisthobranchs. We think they may be Atys ferruginosa (A. Adams, 1850). Perhaps you might have literature references I could check out.
OS0743 - Shell length: 16 mm, Body length: 22 mm
OS0662 - Shell length: 19 mm, Body length: 28 mm
These and others were found in on Pulau Kaledupa and Pulau Hoga in the Tukang Besi Archipelago, SE Sulawesi, Indonesia during 1999 [Operation Wallacea].
Habitat: shallow sand and seagrass / Halimeda beds of these islands. Depth: 4-5 ft between 1900-2100 hours. Photos: Lindsay Warren.
Many thanks for your help.

I wouldn't be surprised if there are names for this animal but it is a juvenile colour form of Atys naucum. I have been planning to add a photo of this juvenile colour form so here is one from northern New Caledonia.
Data: Channel between Récif de l'Infernet & Barrier Reef, off Koumac, New Caledonia, 12m, In lagoon, grey sand, coral slabs , 20 October 1993, 1 specimen, AM C200564. PHOTO: Bill Rudman.
Best wishes,
Bill Rudman
