Marshall Islands Seashell Families

In the search for nudibranchs in the Marshall Islands, we often run into other photogenic creatures, including many of the shelled mollusks. This page links to seashell families we've had time to process for this website. More may be added and some of these groups updated periodically as we get the time. Live animal photos are used where available, and some photos of empty shells have been included to try to fill out the known species in the area. The intent is not to provide perfect photos of perfect specimen shells, but to illustrate what we have seen in the Marshalls, with the photos included as a check on our species identifications. Much remains to be done. Follow this link to see a list of recent modifications to these web pages. Our list of Kwajalein Mollusca in Microsoft Excel format can be found here. This list contains habitat and abundance information on all the gastropods, bivalves, chitons and scaphopods we know of from this atoll. The listing is incomplete and often a bit out of date; it is a work in progress and is updated periodically, consequently its format is somewhat rough. (NOTE: Where sizes are given underneath the species name at the top of the page, it refers to the maximum size of that species we have measured, not necessarily the size of the figured specimens.)
