Chromodoris sp. 15 (in NSSI 2nd Ed, page 140)

Another newbie - Way to go Ali. This new critter is one of about a dozen and a half undescribed species thought to belong to the genus Chromodoris. Species in this genus lay a flat egg ribbon, lying attached to the substrate on its side, rather than upright.

A bit on the small side, reaching only about 18mm in length, the ground color is opaque white, covered with numerous brown-black spots. Its marginal band is orange and broken. The rhinophores and gill are orange to dark red with white spots.

Seen here on the left what is likely its prey sponge. This species is known from the Philippines, New Caledonia and now Papua New Guinea.

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!

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.
