The Biology of Sponges
 Imagine an animal with no mouth, no digestive system, no excretory or circulatory organs, no brain nor nervous system, and no movement as an adult. In spite of their simple nature, sponges are actually one of the most fascinating animal phyla, when viewed in developmental, ecological, and evolutionary terms. Through animations and timelapse microscopy, this program clarifies the structure, function, classification, and ecological roles of sponges.
