Sea squirts are invertebrates known officially as tunicates, and there are more than 3,000 known species. They come in a variety of colors and shapes, but they're typically cylindrical.
They live on rocks, coral and other hard surfaces on the ocean floor, and they feed on plankton and other organic matter, which they strain fro water pumped through their bodies.
