Abstract
Members of the genus Pagurapseudes occupy vacant microgastropod shells. Functional and behavioral convergence with paguridean decapods (hermit crabs) is treated using a combination of gross morphological, histological and scanning electron microscopic analyses, as well as observations of living animals. Post-embryological development is described and compared with that of other tanaidaceans. The proposed life history differs from that of other tanaidaceans in several respects and is the first described for any member of the suborder Monokonophora based on investigations using experimentally reared specimens. Variations in a population over the course of 1.5 years are discussed as are apparent habitat preferences. Preferences of Pagurapseudes for different shell species are examined with respect to shell morphology, size and availability.
