This has been high on my "must see" list for a long time. Our first and so far only specimen of this easily recognized species was found on 13 August 2011 in a Kwajalein Atoll lagoon Halimeda patch. It was crawling in the open between algae clumps at a depth of about 8m. The animal was not measured, but it appeared to be about 70mm in length.
The shape of the mantle margin is unusual and characteristic of this species.
The underside color with its green network and blue patches is also characteristic.
The photos above and below show the long tail.
A closeup of one of the dark patches on the dorsum reveals a pattern of red blotches surrounded by red-rimmed blue dots.
