Dear Greg, Here in Victoria, Australia I have occassionally seen large numbers of Pinnotheres hickmani (Guilen, l950) in Mytilus edulis planulatus. Might have trouble finding or getting them to you but can try if interested Geoff Macaulay >From: Greg Farley <[log in to unmask]> >Reply-To: Conchologists of America List <[log in to unmask]> >To: [log in to unmask] >Subject: Pea crabs symbiotic with molluscs >Date: Wed, 28 Nov 2001 18:37:51 -0500 > >Dear colleagues: > >Hello! By way of introduction, I am a graduate student at Florida State >University in Tallahassee. My research revolves around the evolution and >ecology of commensalism, and I'm using pea crabs (Brachyura: >Pinnotheridae) as a model system. Many species of pea crabs are molluscan >symbionts, and I write to you with the hope that you might be able to help >me collect pea crab specimens for gene sequencing and phylogenetic >analysis. > >Several pea crab species in the genera Fabia and Pinnixa are associated >with bivalves, gastropods, or limpets in the Pacific, typically between >Alaska and the Gulf of California. Others are symbionts of molluscs in >the subtropical Atlantic and Gulf of Mexico. It is my hope that some of >you will be familiar with these crabs, even simply as "incidental" >symbionts of the molluscan taxa with which you work. > >If you would be willing to collect crabs, or know of someone who might, >please contact me. I've included a complete list of "wanted" taxa below, >with hosts and species ranges where known.
