Habitat

Sea cucumbers are found in nearly every marine environment, but are most diverse on tropical shallow-water coral reefs. They range from the intertidal, where they may be exposed briefly at low tide, to the floor of the deepest oceanic trenches. They only avoid areas exposed to high wave action, and are found on all types of bottom, from muddy sand to bedrock.

Although sea cucumbers spread out in the marine environment, all sea cucumbers are ocean dwellers, though some inhabit the shallows and others live in the deep ocean. They live on or near the ocean floor—sometimes partially buried beneath it.
