Ardeadoris? from Hachijo Island Japan

October 27, 2001
From: Nishina Masayoshi


Dear Dr.Rudman,
I thought that this animal was a juvenile of the Glossodoris pallida, but now I wonder if it is instead a juvenile of Ardeadoris egretta. It does not have the characteristic pattern which G. pallida has on the surface of that animal's body. But, the gills don't seem right for A. egretta. Perhaps it is for example something else, perhaps a kind of Noumea?

Data:
Date: 21 Oct, 2001
Location: Hachijo Island Japan
Depth: 6m
Length: 10mm

Best Regards,

Dear Nishina,
There are quite a few species which are white with yellowish markings so you are right to be cautious in identifying them. Despite the lack of the characteristic white markings on the back I think this is a juvenile Glossodoris pallida. Sometimes the marking is not that obvious in living animals, and in other cases, animals with very visible markings in life seem to have completely lost them in photos.

There is always the possibility though that it is something different. Only a look at its radula would resolve that doubt.
best wishes,
Bill Rudman
