Phyllidia exquisita from West Papua

May 24, 2007
From: Jim Anderson

Dear Bill,

Could this animal be Fryeria rueppelii? The yellow edge to the mantle does not appear to extend all the way round nor be as pronounced as other examples on the Forum. The images were taken by me during a recent trip to Raja Ampat in West Papua, Indonesia and some details follow

12 March 07; depth, 15 metres; site East Fam Wall, Penemu Island; coral reef slope ; length 35 mm

Kind regards,

Dear Jim,
My first thoughts were F. rueppelii but the orange border only around the anterior end is a character of Phyllidia exqusita, as are the small whitish granular glands all over the mantle.

Best wishes,
Bill Rudman
