Dear Bill,
I think this 2 shots may solve a problem. The upper photo looks like Hypselodoris sp. 7 . The lower one is a typical Hypselodoris maritima. I think thses show that Hypselodoris sp. 7 is a no-lined colour form of H. maritima.

Spotted animal: Gato Cave, Malapascua Is. Philippines.  Depth: 9 m. Length: 22 mm. 04 May 2005. Lined animal: Gato Wall, Malapascua Is. Philippines. Depth: 20 m. Length: 22 mm. 05 March 2005. Photos: Erwin Koehler

Dear Erwin,
Thanks for these photos. It looks like Nerida Wilson's suggestion [message #8718] about Hypselodoris sp. 7 was right. Certainly your spotted animal , if we ignore the spots, fits H. maritima in external features. Also the mantle glands - individual sacs scattered around the mantle edge except anteriorly - are identical to those in many of the photos of lines H. maritima on the Forum. In Mabel Fang's photo [message #8648] I had thought the yellow border, right against the blue, at the mantle edge, and the numerous black spots on the blue, were rather different from H. maritima, but your animal showing a few black spots on the blue, and other photos on the Forum showing the yellow border sometimes against the blue in H. maritima, suggest these differences are variations rather than distinct differences.
Best wishes,
Bill Rudman
