The large first dorsal fin is positioned about halfway between the pectoral and pelvic fins; the second is almost as large as the first and much larger than the anal fin. The leopard shark occurs in the Northeastern Pacific Ocean, from the temperate continental waters of Coos Bay, Oregon to the tropical waters of Mazatln, Mexico, including the Gulf of California. Leopard sharks have small mouths and teeth, perfect for feedings on crustaceans and bony fish. These rest on top of a light brown background. This is an adaptation for obtaining enough oxygen in deoxygenated estuarine environments.
