Predatory fish are a type of fish that hunt and feed on other animals. Sharks, GAR, PIKE, eels, and ANGLER fish are all examples of predatory fish. Sharks are large, carnivorous fish with a cartilaginous skeleton and five to seven gill slits. GAR are long, slender fish with long snouts and diamond-shaped scales. PIKE are long, slender fish with a flat head and long dorsal fin. Eels are elongated fish with smooth, slimy skin and no scales. ANGLER fish are deep-sea fish with a long dorsal fin and a bioluminescent lure on their heads.
