At sexual maturity, mudpuppies can be 20 cm (8 in) long and continue to grow to an average length of 33 cm (13 in), though specimens up to 43.5 cm (17.1 in) have been reported. [7] Their external gills resemble ostrich plumes and their size depends on the oxygen levels present in the water.
They are moderately robust and have two pairs of short but well-developed limbs and a large, laterally compressed tail. Lungs are present but small.

The list below largely follows Darrel Frost's Amphibian Species of the World (ASW), Version 5.5 (31 January 2011).

Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane , such as modern reptiles , birds and mammals ).
Temnospondyli (from Greek τέμνειν, temnein 'to cut' and σπόνδυλος, spondylos 'vertebra') or temnospondyls is a diverse ancient order of small to giant tetrapods—often considered primitive amphibians—that flourished worldwide during the Carboniferous, Permian and Triassic periods, with fossils being found on every continent.
