Dive-site story
Stretching along the volcanic coastline just south of Tulamben proper, Seraya and Sidem are premier muck and macro territories. The gently descending dark sand and pebble slopes host bizarre critters that thrive in sediment-heavy substrate. Divers slowly comb the seafloor, discovering rare crustaceans, cryptic cephalopods, and tiny nudibranchs tucked against isolated coral heads and rubble patches.
