Eunice furcata has the same habit in the Dry Crustaceans are exceedingly abundant in the reefs, variously con- cealed in cracks and between the branches of the madrepores. The alpheids, or pistol crabs, small, long-tailed decapods which make a snapping sound with their claws (Fig. 46), are closely correlated with the corals in their distribution. Out of 79 long-tailed decapods taken by Gardiner in the Maldive reefs, 76 were alpheids. Crabs are abundant, especially the small Cyclometopa. The family Trapeziidae (Fig. 47) is confined to coral reefs, where single species are restricted to single reefs and occur only on single kinds of corals, as Trapezia
