Hi Bill and everyone!
While we're on the subject of Halgerda... here are some photos another equally beautiful and medium sized nudibranch to add to the Forum's collection. Halgerda tessellata. I have included a really nice ventral view where you can see all the features!
Locality: Mooloolaba, Sunshine Coast, 15 m, Queensland, Australia, Pacific Ocean, 11 November 2008, Subtidal. Length: 18-27 mm. Photographer: Gary Cobb.
Cheers
Gary

These photos show what I consider to be the Western Pacific colour form of the species. You will note the white specks and spots are realtively small except in a wide band around the mantle edge. In the Indian Ocean form the white spots are evenly spread over the brown parts of the mantle with no marginal concentration.
Best wishes,
Bill Rudman
