Opisthobranch of the Week Data
Noumea romeri is considered to be rare on Okinawa as I have seen and collected a total of only two individuals from the main island of Okinawa. In looking over early field notes, I perhaps missed collecting additional specimens as I thought I was, in several cases, looking at what appeared to be juvenile Hypselodoris bullocki, which are superficially similar in appearance. These could well have been Noumea romeri. Bill Rudman (1999) has some of the color variations of H. bullocki posted on the Sea Slug Forum.
Atsushi Ono reports the above featured animal is one of more than five which he has seen in the Keramas* (per. com.). The animal was photographed by Atsushi in March of 1998 from a rock located at the Tonaka Dive Point of Zamami Island. I'm featuring Atsushi's Kerama animal here, with his kind permission, as his photograph is superior in quality to my own.
As of mid-January, 2002, there are ten described species of Noumea known from Okinawan waters:
* Keramas = the Kerama Islands Group, located 30 ~ 40 kilometers west of the Okinawa capitol, Naha.
