Colpodaspis thompsoni from Kerama Id

February 4, 2000
From: Atsushi Ono


Dear Bill,

Here are some animals which I cannot decide whether they are Opisthobranchs or not.
I found this species at the reef edge and in a bay, about 5m depth. [at Kerama Is. near Okinawa in Japan].

They have eyes at a root of a siphon. They have shells, and their length is 2 to 3mm.
What is this species?

Sincerely,
Atsushi Ono

Dear Atsushi,
At last I can identify an animal for you. It is Colpodaspis thompsoni which Greg Brown first discovered while he was visiting me in Tanzania in 1976. I look on this species as an 'old friend'.

Unfortunately we know nothing of its biology. It has sometimes been found in eastern Australia and I found one specimen in New Caledonia.

Best wishes,
Bill Rudman.
