Hi Bill,
Further to the messages from Oren [#13208] and Marina [#13308], and your own observation [#13303 ] that Thuridilla sp. 3 may be Thuridilla indopacifica: Here are specimens from 2 more dive sites in Eilat. These have recently (and quite suddenly) become common in Eilat and can be found at many sites at various depths.

The upper photo shows rhinophore coloration similar to the previous reports. The lower photo shows another specimen with a variation of the rhinophore coloration (at least on the one he doesn't have hidden from us): it has no white band to speak of, the speckled green continues until it meets a blue band, then black/orange/black, and then again no white band, but rather just the blue tip.

Locality: Eilat, Israel, Red Sea .Depth: 36 m and 22 m. Length: up to 15 mm. 11 March 2005. corals. Photographer: Binyamin and Shulamit Koretz

Regards
Binyamin
