Sea Spiders: Pycnogonida

Diet

Most sea spiders eat other animals and attack invertebrates (in-VER-teh-brehts), or animals without backbones, that are attached to the ocean bottom, such as corals, clams, and marine worms. A few species feed on red algae (AL-jee), a special group of plantlike ocean life that lacks true roots, stems, or leaves. Other sea spiders feed on bits of plant and animal tissues that build up under colonies of invertebrates. While some species use the teeth at the tip of the proboscis to pierce the bodies of their prey and suck out their juices, others tear their victims apart and feed on the small pieces.
