These are Salamanders and live an entirely aquatic lifestyle. They have flattened limbs for slowly walking across the bottom but can also have short swimming spurts.
Their external gills resemble ostrich plumes and their size depends on the oxygen levels present in the water, if the water is stagnant their gills will be larger than in clear flowing waters. Ref: https://en.wikipedia.org/wiki/Common_mudpuppy
