Largest member of the pike family, the muskellunge, Esox masquinongy, is found mostly in the Great Lakes region of North America. It formerly was known from eastern and central Canada to the upper Ohio Valley. With a duckbill-like snout containing large, conical teeth, the muskellunge is a predatory fish distinguished from pike and pickerels by its large size, up to five feet (1.5 m) long. It can way up to 70 pounds (32 kg). The muskellunge spawns in early spring, scattering eggs into weedy shallows of tributaries. This fish is popular with anglers.
