Seamounts, A Deep-Sea Habitat

Thousands of seamounts—most of them undersea volcanoes—tower above the muddy seafloor. They provide something hard to come by in the deep ocean: a solid surface to cling to. This photo gallery shows some of the organisms that have found a suitable home on seamounts. 

A variety of corals cling to Manning Seamount, just off the coast of Cape Cod, Massachusetts.
