Ceratosoma sp. 3 undescribed-(in the new Nudibranch & Sea Slug Identification, due out soon)(= sp. 2 in the old Indo-Pacific Sea Slugs)
The genus Ceratosoma has some of the most colorful of the dorid nudibranch species. This undescribed species is red with longitudinal white lines and a wide marginal band opaque white. The rhinophores and gill white with red lines. This species falls into the group with a flat dorsum, lacking lateral lobes as in Ceratosoma tenue and C. trilodata (Both links courtesy of Bill Rudman's Sea Slugh Forum); its mantle edge is undulating.
Known only from Indonesia, individuals may reach up to 20mm in length and may be found on coral reefs in shallow water.
Wouldn't it be great if we found this guy in Anilao at our Nudibranch Workshop next March!
