Elysia rufescens (Pease, 1871)

This is one of several of Mary Jane Adams's photos in the New - Reef Creature Identification - Tropical Pacific, by Paul Human and Ned DeLoach. Originally described with only a color drawing (Courtesy of Bill Rudman's Sea Slug Forum), this is one of the prettier Elysia's. The body is green with white blotches. The parapodial margin has blue band followed by an orange submarginal band. Like other Elysia's the rhinophores are rolled. This species has a wide geographic distribution that includes - the western Indian ocean of South Africa and Reunion, to Thailand, Myanmar, Christmas Island, Australia, the Philippines, Japan, Guam, Samoa, Tahiti and Hawai'i. A sap sucking slug, it feeds on filamentous algae, with its series of single rachidian teeth. Remember the taxonomic category Sacoglossa , to which Elysia belongs, is named for the "sack" in the throat or "glossa" that captures worn teeth, as they fall out. Specimens may reach up to 60mm in length.

Nice shot Mary Jane!

Mary Jane Adams

As with the Pellets of last week's BOW, Mary Jane Adams of Arcadia, California is a long time contributor to the Slug Site. Many of her images have been truly inspirational in my personal quest to see as many sea slugs as possible in this lifetime. In particular, I am talking about the images of Kalinga ornata Mary Jane first sent in back in 1999. Mary Jane's pictures of this bizarre creature set up a wanderlust to see K. ornata that finally culminated in seeing it at the Anilao Pier during a night dive at Anilao, Batangas, Philippines in May of this year, some eleven years later!

Mary Jane is currently enjoying retirement diving around the world photographing our friends the sea slugs! When not diving Mary Jane serves on the Board of Trustees for the Aquarium of the Pacific, in Long Beach California. She has also served a volunteer in Opistobranch studies for both the California Academy of Sciences and the Los Angeles County Museum. More recently she coordinated and assisted in the selection/identification phase of the Opistobranch section of Paul Humann and Ned DeLoach's new book (above)!
