Did you know there are more than 370 different species of sharks? Here is my shark report about the Cookie-cutter shark. Its physical features are its brown belly, blunt snout, and razor-sharp teeth. Its about 20 inches long with large eyes. This shark lives in deep tropical ocean waters all over the world. It swims at depths of about 3500 meters. It eats dolphins, whales, and large fish. This shark can emit a green glow from its belly. What an unusual and interesting shark!!!
