Re: Hypselodoris krakatoa? from Taiwan

Dear Bill,
This animal from Taiwan is Hypselodoris krakatoa Gosliner & Johnson, 1999. Recently Rebecca Johnson the animals in these photographs (Hachijo type), to be H. krakatoa. I hope Rebecca Johnson will say something. It seems there is one color pattern of H. krakatoa in the Indonesia - Malaysia region and another pattern further north [Taiwan, Ryukyu Islands Group and Hachijo Island].

I also suspect my animal that I posted before and you identified as Hypselodoris sp. 6 may be H. krakatoa too.

Date: 9 June, 2002
Location: Hachijo Island Japan
Depth: 6m
Length: 30mm
It's common at Hachijo Island.

Best Regards,
Nishina Masayoshi

Thanks Nishina,
I agree that then animal I called Hypselodoris sp. 6 is the same as your animal. In your earlier specimen there was no sign of the white spots which seem to be the link between the Japanese-Taiwan colour form and the much browner Malaysia-Indonesia colour form. Rie Nakano's animals, which I previously doubted were H. krakatoa, show the white spots along the purple longitudinal lines, and are clearly the same 'colour form'.
Best wishes,
Bill Rudman
