The mudpuppy jaw is considered metaautostyly, like most amphibians, meaning the jaw is more stable and that the salamander has a dentary. [15] This affects their diet by limiting the flexibility of the jaw to take in larger prey. The mudpuppy has few predators which may include fish, crayfish, turtles, and water snakes. Fishermen also ...
This may be a species complex that could be split into different taxa as research indicates; [3] the Apalachicola (N. moleri) and Escambia (N. mounti) waterdogs were split from this species in 2020; previously, they were all grouped together as the Gulf Coast waterdog. [2]
It eats mainly small underwater animals. Its feathery gills mean that it can breathe only underwater not on land. It and many other mudpuppies can still go on land, but not for a very long time. They go on land only if the water is too dirty so they can find cleaner water in another part of the river.
Adults feed from the mouths of their retreats or move about in search of prey at night. Olfaction and sight play important roles in locating food. Animals are active away from cover at night, and also during raised water levels and increased turbidity. Individuals are inactive when stream temperatures exceed 18 °C.

Necturus occur in surface waters, preferentially with clear water and rocky substrates without silt. N. maculosus live in lakes, rivers, streams, and creeks. [15] [16] They like shallow waters with low temperatures from autumn to early spring. [15] They are most active in cold temperatures, specifically between 9.1 and 20.2 degrees Celsius.
The care of offspring among amphibians has been little studied but, in general, the larger the number of eggs in a batch, the less likely it is that any degree of parental care takes place. Nevertheless, it is estimated that in up to 20% of amphibian species, one or both adults play some role in the care of the young. [ 128 ]
