Sea cucumbers live all over the world.

Sea cucumbers live in all sea habitats, ranging from areas exposed at low tide to the bottom of the deepest part of the ocean. Some species live on wave-hammered reef crests and rocky shorelines. Many species live on hard bottoms. Others burrow in sand or mud. Some species swim miles above the sea floor.

Sea cucumbers eat algae, plankton, bacteria, and waste particles. Algae (AL-jee) are plantlike growths that live in water and have no true roots, stems, or leaves. Plankton is microscopic plants and animals drifting in water.

Sea cucumbers are not considered threatened or endangered.
