Mating is believed to happen during fall but the females don’t lay the eggs right away. Females store the sperm inside them throughout winter until the temperature starts to increase.

The Common Mudpuppy is nocturnal and hunt during the night while they hide in their burrows during the day. They have teeth that are used to hold prey in their mouth as they usually just suck in the prey into their mouth.

The International Union for the Conservation of Nature (IUCN) Red List categorizes the Common Mudpuppy as Least Concern for Extinction. They have a wide range and a large population. Only threat to the mudpuppy is the pollution and sedimentation of the waters they live in.
