What is a "mudpuppy"?

A mudpuppy, also known as the waterdog, is a fascinating amphibian found in freshwater habitats of North America. It has a unique appearance, with a stout body, smooth skin, and external gills that allow it to breathe underwater. Mudpuppies are primarily nocturnal and are known for their ability to regrow lost body parts. They have strong jaws and feed on a variety of prey, including insects, small fish, and crustaceans. Despite their somewhat intimidating name, mudpuppies are harmless to humans and play an important role in maintaining the ecological balance of their aquatic habitats.
