The Misunderstood Mudpuppy
Mudpuppies are Michigan’s largest, fully aquatic salamander. Often referred to as ‘bio-indicators’ because they are sensitive to pollutants and water quality, these salamanders act as an early warning system for environmental problems.
​
Mudpuppies are actually an amphibian and although they have lungs and can gulp air they rely on their feathery red external gills for oxygen.​
​
Their diet is mostly crayfish, insect larvae, snails and small fish. There is no evidence that they impact fish populations, and they more likely benefit them by helping control non-native species.
​
Mudpuppies are a protected species in Michigan. People sometimes accidentally catch them while fishing. If you do catch a mudpuppy, you must put them back.
​
Mudpuppies are not blind, but their eyesight is limited. They rely on a keen sense of smell to find their prey.
​
Female mudpuppies not only protect their eggs until they hatch but will also guard the nest while the young emerge and disperse.
​
Although slimy, mudpuppies are not poisonous. Anglers should gently remove the hook and return them to the water.
