About this site
The Crevice is located along the coast of Guam, the largest island in the Mariana Archipelago in Micronesia. Dive sites along this coastline are typically reached from shore or by short boat trips out of the island's western or southern harbors, where the fringing reef drops toward deeper Pacific water. Divers here have reported dusky surgeonfish, jewel damsels, lined bristletooth, Pacific bullethead parrotfish, Pacific orange-spine unicornfish, princess damsels, and Tracey's damselfish, along with plate and pillar coral and spotted linckia sea stars along the reef.
