Marshall Islands Sea Slugs

Our favorite close-up photo subjects are the sea slugs, including nudibranchs and their relatives. More than 400 different kinds have been found in the Marshall Islands, not all of which are yet represented by pictures on this site.

We have many years of diving experience in the Marshalls, including many thousands of hours in the water. Most of this has been at Kwajalein Atoll, from which we have also travelled to nearby Namu Atoll and isolated Lib Island. One of us spent several years at the Mid-Pacific Research Lab on Enewetak Atoll, including two research trips there in the 1970s and a stint as a member of the lab staff in the early 1980s. While a member of the lab staff, research trips were also undertaken to Bikini, Rongelap, Utirik, and Ujelang Atolls in the northern Marshalls. For much of that time, we have been on the lookout for sea slugs, both for scientific study and for the pure enjoyment in their colors, shapes, and fascinating natural history.

Each of the thumbnails below takes you to another page that contains a list of links by scientific name. Those links lead to pics and a bit of information about each of the different species.

Despite the years of searching, we continue to see species here that we have not before seen, so with luck this page will continue to be updated.

If you have comments or disagree with any identifications, don't hesitate to contact us at uwkwaj@yahoo.com. And if you're in or have been in the Marshalls and have seen species you cannot find on these pages, we'd like to hear about it.
