Three species of Libinia inhabit the coastal and estuarine waters of the Western Atlantic and Caribbean Oceans: L. dubia; the portly spider crab, L. emarginata; and the seagrass spider crab, L. erinacea. The color and shape of all species are similar, and discrimination between juvenile specimens can be difficult. However, Libinia dubia and L. emarginata are distinguished by the number of dorsal median spines, bearing six and nine, respectively (Abele & Kim 1986). The maximum size of the portly spider crab is also slightly larger than that of L. dubia (Ruppert & Fox 1988). The rostrum of young seagrass spider crabs forks more deeply than L. dubia, and the horns curve toward one another (Abele & Kim 1986). II . HABITAT & DISTRIBUTION
