Siphopteronsp. 6 (Undescribed)

Dave is on break so you're stuck with the webmaster this week!

This week we once again feature photography by Ali Hermosillo McKowen, underwater branch photographer and sea slug finder par excellence!

Siphopteron are one of my favorite subjects when I am fortunate enough to run across one! They have a unique mode of locomotion among sea slugs that when on the move certainly lends itself to videography.

This guy is my pat answer when asked why I prefer video over still photography when recording my encounters with sea slugs. Years ago I put together a video for veteran PNG traveler John Greenamyer! Two versions of this show have been uploaded to my Hightail Site! The show runs about 16 minutes so if you are pressed for time, the relevant clips for Siphopteron start at 5:16 and 10:42 minutes. John has also included a short clip of his namesake Doto Greenmayeri at 8:37 minutes! The two versions are 1080p (1.32 gigs) and 720p (691 Mb)! Depending on your bandwidth, you make the selection but I would recommend the 1080p version if you can make the stretch!

Both versions will be available for viewing until August 31st.

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!

What more can be said, Ali is the greatest!

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.
