Tambja cf. sp. 3 (in NSSI 2nd edition)

Marta Pola and company in their 2005 and 2006 papers have cleared up many of the confusing Tambja species and added a few new ones. This species still remains undescribed.

David had originally identified this critter as Tambja victoria, but there are numerous differences which disqualify that ID, most notably the three yellow-orange strips on the body and yellow rings at the base of the rhinophores.

This undescribed Tambja has numerous green longitudinal body stripes, a few of which may be broken, and green rings around the base of the rhinophores. The gill, too is yellow green anteriorly.

Nice pics David.

The Indo-Pacific represents the largest expanse of tropical ocean in the world, stretching from the Indian Ocean coast of southern Africa and the Red Sea to the central Pacific of the Hawaiian Islands, Easter Island and the Marquesas.

This region supports the most diverse marine fauna of any place in the world for most groups of marine organisms. The nudibranchs and sea slugs are no exception to this rule; there are about 3,000 described species of these organisms in the world and at least 40% of these have been found exclusively in the Indo-Pacific tropics. This book illustrates 2,138 Indo-Pacific nudibranchs and sea slugs, including many undescribed species.
