Bubble shell from Kerama Island

From: Atsushi Ono

Dear Bill,
How did you enjoy your holiday? I enjoy my winter holiday now.

Thank you for ID of my photo Hamineobulla kawamurai.

Here is another cephalaspid species from Kerama Is, near Okinawa, Japan. It was 4m deep, on a rope covered with algae and sponge. Shell length is 4mm. This animal moved very slowly. It has small brown and milk white dots on its translucent headshield and body.

Could you help me to identify this species?

Sincerely,
Atsushi Ono

Dear Atsushi,
I must warn you that my identification of your earlier photo as Haminoebulla kawamurai was only tentative. Many of these bubble-shells are only known from their shells, so photos of the live animals are difficult to recognise.

I am not sure of this photo. Perhaps Clay Carlson, who is a specialist with the bubble-shells, will be able to give us some clues. The brown spots on the shell may be a useful character.

I hope your winter holiday is not too cold,
Best wishes,
Bill Rudman.
