Chromodoris aureopurpurea from Japan

Dear Bill
Because there is not a report on the Forum from Japan, I send it. It resembles the photo of Chromodoris aureopurpurea of Hong Kong.

Those are common sea slugs there, but I am happy if those are helpful for you. Thet are from Echizen coast (Tsuruga Bay, Japan)

UPPER RIGHT: Depth: 5m, Size: 25mm
Water temperature: 26-28C degrees.
LOWER LEFT: Depth: 5-7m, Size: 30-40mm
Water temperature: 26-28C degrees.
LOWER RIGHT: Depth: 5-7m, Size: 30-35mm
Water temperature: 26-28C degrees.

Dear Jun,
Thanks for these interesting photos. Even the most common Japanese species are of interest because so many species of the many species descrbed by Dr Kikutaro Baba from Japan, have a much wider distribution throughout the tropical Indo-West Pacific. So for anyone working on that Indo-West Pacific fauna it is vital to understand the Japanese fauna so we know whether a species we have found in Australia or South Africa has already been named from a Japanese specimen.

Best wishes,
Bill Rudman
