Abstract
Crabs collected with a cage trap or hand net in submarine caves around Koror Island in the Palau Islands were identified as the following six species: Schizophrys dahlak GRIFFIN & TRANTER of the Majidae, Carupa ohashii TAKEDA, Charybdis paucidentata (A. MILNE EDWARDS) and Laleonectes nipponensis (SAKAI) of the Portunidae, and Lentilumnus latimanus (GORDON) and Pilumnus sp. of the Pilumnidae. Of these species, S. dahlak had been reported only from the Red Sea, and Ch. paucidentata from the western Indian Ocean including the Red Sea and the Persian Gulf. Species of the Majidae and Portunidae seemed to be typical inhabitants of the submarine caves.
