Hypselodoris from Hachijo

April 9, 2002
From: Rie Nakano


Dear Dr.Rudman,
I found this Hypselodoris at the top of the rocky reef of Hachijo Island, Izu, Japan, in 27th, September, 2001. At first, I thought this animal was Hypselodoris krakatoa, but the background color of this animal is pale beige, mantle edge color is light purple, has not bright white spots. The gills are without white spots up the outer edge of the rachis.
Is this H.krakatoa? Or another spacies? Mr. Masayoshi Nishina says this one and his Hypselodoris sp. are the same species.

Depth:15m
Length:30mm
Water temperature:24.6 degrees
Frequency: common in Hachijo

Sincerely,
Rie Nakano

Dear Rie,
I would agree that this is the same as Nishina's photo. I don't think it is a colour form of H. krakatoa. Temporarily I will call it Hypselodoris sp. 6.
Best wishes,
Bill Rudman.
