Answer
Filter feeders like sponges are most often sessile organisms that sift through water to pick out small prey. Non-sessile filter feeders include chordates such us urochordata or whales. Predatory animals always have sensory organs that allow them to locate prey. They are often fitted with canines that help them slash and tear meat. Parasitic animals are often small and have specialized features for attaching to and siphoning nutrients from prey. For example, leeches possess many sharp teeth that are designed to latch onto hosts.
