The apparent habitat isolation of the mudshrimps Callianassa islagrande Schmitt and Callianassa jamaicense louisianensis Schmitt (Anomura : Thalassinidea) in Mississippi Sound is a function of species-related differences in ability to burrow and survive in the significantly different substrates of each habitat. C. islagrande is found only in sand bottomed beaches of the offshore barrier islands, whereas C. j. louisianensis is found only in the muddy backwaters of the mainland and Deer Island. Both forms produce deep and extensive permanent or semipermanent burrows in their respective habitat and are probably of some significance in sediment turnover. Laboratory studies show that C. …
