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]
[15] [16] The common mudpuppy never leaves its aquatic environment and therefore does not undergo morphogenesis; however, many salamanders do and develop differentiated teeth. [17] Aquatic salamander teeth are used to hinder escape of the prey from the salamander; they do not have a crushing function. [17] This aids the salamander when feeding.
The family Proteidae is a group of aquatic salamanders found today in the Balkan Peninsula and North America. The range of the genus Necturus (commonly known as waterdogs or mudpuppies) runs from southern central Canada, through the midwestern United States, east to North Carolina and south to Georgia and Mississippi. [1]
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.
Most taxonomic authorities currently consider this salamander to be a subspecies of the common mudpuppy (N. maculosus): N. maculosus louisianensis, or the Red River mudpuppy. The Red River waterdog was proposed as a separate species from the common mudpuppy by Collins in 1991, [ 1 ] but supporting data was lacking.

The barred tiger salamander typically grows from 7.6 to 16.5 cm (3.0 to 6.5 in), but neotenic forms can grow to lengths of 17.8 to 38.1 cm (7.0 to 15.0 in), [3] and is one of the largest species of salamander in North America. It has a broad head and a sturdy body.
