Chondrichthyes are jawed vertebrates with paired fins, scales, teeth, & skeletons made of cartilage. For 400 million years, cartilaginous fishes evolved into one of the most successful groups of marine fishes today. We will survey the diversity of this group that radiated into nearly every aquatic habitat. Many species are at risk of extinction. Discussions will center on measures aimed to help. Course for 6th-12th graders. If you cancel less than 48 hours before the class, no refund will be given.
