Description:
Length in Kansas up to 10 inches. Very similar to the closely related Western Tiger Salamander in size and appearance, but with much smaller spots that seldom form elongated bars. The spots are never in any set shape, size, position, or pattern. They have a rather large head and a broad rounded snout. Their eyes are round, and their belly is usually yellowish with dark pigment encroaching along the sides.
Adults normally 180-210 mm (7-8¼ inches) in TL; largest adult specimen from Kansas is unknown; maximum length throughout range: 13 inches (Conant and Collins, 1998).

Distribution:
Most records were recorded from the Kansas River drainage basin east of Shawnee County. This is the rarest salamander in Kansas.

Natural History:
They live underground most of the year and dig their own burrows, unlike most other species that utilize burrows of other animals. This allows them to escape the temperature extremes on the surface and may explain why they have such a wide array of habitat types. They are seldom reported in Kansas and persist in small localized populations.
Hartman (1906) reported on three larvae that contained respectively, four, seven and two water-boatman. He discovered an adult which had consumed a ground-beetle.

Remarks:
The status of this salamander is enigmatic. Most of its known localities are within the Kansas River basin; however, even there, it is uncommon. It is doubtful that landscape changes over past 50 years have had much effect on the distribution of this taxon in Kansas. It is more likely that the populations that do exist are localized, and therefore difficult to sample.
Additional survey efforts are needed to better understand the status of this salamander in Kansas. Activities such as seining small ponds, employing pitfall traps, and road cruising on rainy nights (particularly in the fall) should yield the best results.
