Mudpuppies - Waterdogs Don't Bark

head gills


Amazing amphibians - mudpuppies (or sometimes "waterdogs") are water dwelling salamanders who get their unique name from the old (and incorrect) notion that they make a "barking" sound, much like a real dog! Most of the species of mudpuppies live in a straight line down the center of North America, as far north as central Canada, and down eastward into Mississippi and Georgia. Distinguishing them from other salamander species, mudpuppies never "grow out" of their gills, and instead keep them for life - they have lungs, as is required to be classified an amphibian, but they appear to not use them, instead spending their whole lives submerged in water. Their aquatic lifestyle is sustained by a diet of snails, crayfish, worms, fish eggs and any other small creepy-crawlies that live in the mud and under the rocks where mudpuppies dwell.

Mudpuppies like to live in streams, slow moving rivers and shallow lakes, but reports indicate that individual cases of mudpuppies living in water as deep as 90 feet are not too uncommon. Some of the individual species (such as the Alabama Waterdog) are considered endangered, and efforts have been made to protect at-risk species.

Sizes of these cool aquatic carnivores vary, most averaging between 20-30 centimeters (8-12 inches). Amazingly, they generally take upwards of six years to reach sexual maturity, when females can lay up to 200 eggs at a time.
