Boy - Ali can sure find them. This species was originally placed in the genus, Tambja. Its trivial name is intended to draw attention to the long oral tentacles.
Specimens colors vary greatly but in general the body is yellow to yellowish-green with several longitudinal blue lines edged in black. The rhinophores, gill and oral tentacles are deep blue to black.
Green specimens with yellow stripes shown on the Sea Slug Forum listed as T. tentaculata Pola, Cervera & Gosliner, 2005 are most likely Tambja sp. 7 in NSSI 2nd Ed (page 46).
Members of the genus Roboastra feed on other polycerid nudibranchs, while Tambja's feed on bryozoans. Nasty habit.

Ali Hermosillo McKowen on location in the Philippines
Ali needs very little in the way of introduction to readers of this site. She has been featured in many of the Branch of the Week (BOW) presentations through the years. Diving with Ali can be infectious assuming you can keep up with her. If you didn't have an appreciation for our friends the sea slugs before diving with her, you will certainly reach quantum levels in that regard as Ali is all consuming in her quest to photograph and document their behavior! In the last few years she even acquired her Doctorate in Opistobrach Studies so her enthusiasm certainly knows no bounds. She has the material for putting together field guides for both the Milne Bay region of PNG and also Anilao in the Batangas area of the Philippines. Let's encourage her when time permits to make that happen!
As a side note Ali has posted ID's with her Flicker postings from both areas. The links can be seen in the left frame of this site. Very worth while to visit for those who are seeking to put names together with images.
What more can be said, Ali is the greatest!

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.
