A mudpuppy is a large, permanently aquatic salamander with bushy, reddish gills visible behind the head. These salamanders inhabit rivers and lakes, including bays and shallows of the Great Lakes. Mudpuppies are sensitive to chemicals used in fish management and are undoubtedly affected by many water pollutants. They spend most of their time crawling on the bottom or hiding under objects in shallow water, but they have been reported to depths of 100 feet (30 m). Mudpuppies feed on a variety of small aquatic animals, including crayfish, snails, insect larvae, worms, and fish.

Male and female mudpuppies congregate in shallow water in October and November for mating, but egg laying does not occur until the following spring. Females excavate a nest cavity under a submerged rock or other flat object. From 50 to 100 or more pea-sized eggs are suspended from the upper surface of the cavity, each hanging from a thin gelatinous stalk. The female stays with the eggs until the larvae hatch. The larvae measure from .75 to 1.4 inches (2 to 3.5 cm) long at hatching and reach maturity in four to six years. Mudpuppies may live for more than 20 years.

Frequently caught by ice fisherman.
