Sea squirts live in all oceans and seas.
Sea squirts live at all depths. Most live in shallow water. Some even survive on open shores under strong wave action. Some sea squirts live in ocean trenches as deep as 28,000 feet (8,400 meters). Most species of sea squirts live on rocks, shells, or algae (AL-jee), which are plantlike growths that live in water and have no true roots, stems, or leaves. Some sea squirts live on soft muddy or sandy bottoms. A few species of sea squirts live between gravel grains.
Sea squirts eat bacteria, plankton, and small swimming invertebrates. Plankton is microscopic plants and animals drifting in the water. Invertebrates (in-VER-teh-brehts) are animals without a backbone.
Sea squirts may be a source for chemicals used to make medicines. In some countries, people eat sea squirts. Sea squirts that grow on the bottoms of ships interfere with mussel and oyster farming.
Sea squirts are not considered threatened or endangered.
