Wyoming Toad
Wyoming Toad: U.S. Fish and Wildlife Service
Mountain-Prairie Region
Wyoming Toad (Bufo
baxteri)
DESCRIPTION:
Adult snout-vent length averages about 2.2 inches.
Females grow slightly larger than males. The dorsal surface of the
body has rounded warts intermediate in size between those of the Great
Plains toad (
Bufo cognatus)
and the Boreal toad (
Bufo boreas)
.
The cranial crests fuse medially to form an elongated boss, a ridge with
a median groove, or paired ridges. The boss is often cornified.
Postorbital ridges are indistinct or absent. The tympanum is round,
smaller than the eye. Cutting tubercles on the hind foot are well
developed. Background color is dark brown, gray, or greenish with
small dark blotches and a rather indistinct median line. Some individuals
have well defined light lateral stripes. The belly is spotted; males have
a dark throat. Photographic analysis has shown that individual toads
can be identified by the variation in their skin color and wart patterns.
