Thorunna sp. 9 (in NSSI 2nd Ed)

Anthony Berberian has contributed over three dozen "new" undescribed species to the First and Second editions of Nudibranchs and Sea Slugs Identification. The last two BOW's BOW 1199 & BOW 1200 are just a couple.

With Anthony's permission here is another absolutely amazing beast - A new Thorunna.

We can clearly see the defensive chemical secreting mantle glands on the anterior and posterior edges of the dorsum. The bright body colors advertise the potency of this highly evolved defensive strategy. What a beauty. If these colors are not an indication to a predator to stop - what is?

No text is needed to describe this species - just enjoy the photo.

Not unlike the amazing impressionistic creations of the French artist Eugene Henry Paul Gauguin, who spent the last ten years of his life in French Polynesia, the waters there seem to be teaming with equally colorful and outrageously gorgeous creatures. Thank you, Anthony.

Attention all you Sluggers, and you know who you are!

This new 2nd Edition is updated and reorganized, including 185 new species. Among other features, the new edition includes additional photographs of species, an identification key, and an up-to-date classification reflecting the latest evolutionary relationships. 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.
