Abstract

and Geryonid crabs are large, benthic inhab- itants of the continental slope, a region char- acterized by darkness and relatively stable conditions of temperature and salinity. They occur in the Atlantic, Pacific, and Indian Oceans (and associated bodies of water) at depths from 100 to greater than 2,800 m. Two or more species may occupy the same geographic range, but regardless of geo- graphic overlap, species are usually sepa- rated bathymetrically. The family Geryon- idae has been recently revised with two new genera and nine new species being de- scribed, and with the genus Geryon being changed to Chaceon (Manning and Hol- thuis, 1989). In the Gulf of Mexico two species of ger- yonids have been described: Geryon (now Chaceon)fenneri, the golden crab, and Cha- ceon quinquedens, the red crab (Otwell et al., 1984; Manning and Holthuis, 1984; Na- tional Marine Fisheries Service, 1986). The distribution, reproductive biology, and life history strategies of both species have been the subject of many recent investigations (Haefner and Musick, 1974; Haefner, 1978; Wenner et al., 1987; Hines, 1988; Hinsch, 1988; Erdman and Blake, 1988; Lockhart et al., in press).
