This incredible PowerPoint is the basis for my unit on sharks. It's a great way to segue into a unit on open ocean, which engaging the students in a fun topic. The idea of a "Shark Week" is a spinoff of the Discovery Channel's week long TV programming that focuses on sharks. The tie into pop culture is a great way to get students excited about the anatomy and physiology of cartilaginous fishes. After reviewing this PowerPoint, students will be able to identify distinguishing structures and functions of most cartilaginous fish and use as a basis for comparison to bony fish.
