PBS offers this companion Web site to Ancient Creatures of the Deep, a recent NOVA documentary about the coelacanth, a fascinating living fossil. Numerous educational activities are provided, covering a range of grade levels. Students can discover how coelacanth anatomy is like that of no other animal alive (grades 3-12), learn about eight other living fossil fishes (grades 3-12), or "relive the excitement" of the coelacanth's 1938 discovery by reading letters between the discoverer Marjorie Courtenay-Latimer and the expert she consulted (grades 6-12). The Web site also includes a 10-question quiz for 9-12th graders (with detailed explanations of the answers), and a printable activity sheet that has students compare and classify the coelacanth in relation to a moray eel and a bull shark (grades 3-8).
