| phylum | Chordata | The common mudpuppy live an entirely aquatic lifestyle in the eastern part of North America in lakes, rivers, and ponds. Mudpuppies go through paedomorphosis and retain their external gills. Because skin and lung respiration alone is not sufficient for gas exchange, mudpuppies must rely on external gills as their primary means of gas exchange. They can grow to an average length of 33 cm (13 in).
