Abstract
Adult ghost shrimp Callichirus islagrande Schmitt 1935 are obligate inhabitants of burrow systems that they excavate deeply into beachfront sediments in the northern Gulf of Mexico Mating presumably occurs in these burrows but has never been directly observed in C islagrande or any other thalassinidean A variety of possible mating systems is suggested by those of other decapods among which are examples of both internal and external sperm deposition sperm competition among males and male adaptations for paternity assurance We used genetic markers to determine if clutches brooded by individual female ghost shrimp had been fertilized by multiple males The two microsatellite loci we employed were sufficiently polymorphic to detect 95 of the occurrences of fertilization by two males Among 40 ovigerous females collected from the Louisiana Isles Dernieres barrier island eight 20 carried egg masses for which more than two paternal alleles were detected indicating fertilization by multiple males In two cases of multiple paternity alleles from one of the males were detected in only a portion of an egg mass These observations suggest several possibly novel characteristics of the mating system that can be further investigatedWe extend thanks to R Bourgeois for help with specimen collection This study was funded by grants from the US Department of Energy grant no DEFG0297ER12220 and the National Science Foundation This is contribution no 101 from the UL Lafayette Laboratory for Crustacean Research All experiments that were conducted comply with current laws of the United States of America
