Tritonia bollandi from Okinawa

From: Bob Bolland


Hi Bill,
Here's an image of the recently described Tritonia bollandi from Okinawa. I've collected a half dozen of these and all would appear to be members of the same species. I've enclosed a second photo of the ova (?, the animal was not found on the eggs and my field notes only say the 'branch was found nearby on the same octocoral).

Data:
Collection #: RFB #3557-A
Location: Seragaki, Okinawa
Collection date: 1 March, 1997
TL: 16mm
Depth: 225ft (69m)

Cheers,
Bob

Thanks Bob,
By coincidence, your message arrived at the same time as Vic's message letting me know that his description, with Terry Gosliner, of this as T. bollandi had been published. It is interesting how the colour of this animal is much more similar in colour to the Indonesian animals than the photos of your on which they based their description. Vic suggests the colour difference may be depth related. Can you give us any information on colour variation in Okinawan animals?
Best wishes,
Bill Rudman
