Branches on the Tree of Life: Sponges DVD

(in stock)


Imagine an animal with no mouth, no digestive system, no excretory or circulatory organs, no brain or nervous system, and no movement as an adult. In spite of their simple physiology, sponges are actually one of the most fascinating animal phyla when viewed in developmental, ecological, and evolutionary terms. Through animations and time-lapse microscopy, this program clarifies the structure, function, classification, and ecological roles of sponges. DVD includes an illustrated PDF teaching guide. Close-captioned. 2005.
