Tiger salamanders are found throughout North Dakota. These salamanders can grow quite large. Adults are commonly found from 6-13 inches long. As the name implies, tiger salamanders are usually bicolored. One color describes the background or body of the animal, while the other color describes the pattem.
Background colors range from gray, black, and brown, to olive green.
The pattens may be spots, bands, bars, or blotches of various sizes, shapes and color. Eastern tiger salamanders exhibit black as a background color and a pattem of yellowish-brown spots that vary in size and shape. Tiger salamanders are often seen at night after a heavy rainfall. This is even more true during the breeding season. Gray tiger salamanders are a common subspecies of the tiger salamander found in eastern North Dakota.
