Dear Dr.Rudman

This animal was found by Mr.Kotaro Tanaka and me at Hachijo Is, Japan, in March, 2002. It seems to eat the green sponge in the lower right photo. Depth: 16m, Length: 4mm
Water temperature: 19.6 degrees

Also Mr.Hideyuki Takasu found color variation of this one [upper right] in Hachijo Is. In September, 2001.
Depth: 15m, Length: unknown, Water temperature: 23 degrees(maybe).

I also found a specimen at Kerama Is. in March, 2001.(No photo). Depth: 10m, Length: 7mm, Water temperature: 20 degrees

I wonder if this is a species of Aegires?

Dear Rie,
It certainly looks like a species of Aegires, but I don't know of a named one with this colour pattern.
Best wishes,
