The Kendall Warm Springs dace (Rhinichthys osculus thermalis) is a speckled minnow subspecies of the speckled dace endemic to the Kendall Warm Springs in Wyoming; the only fish to inhabit the temperate freshwaters. Adults often only reach 2 inches in length.[1] The fish was originally designated as a subspecies due to its distinct morphological features from other Rhinichthys osculus, which arose from its isolation in the Kendall Warm Springs within which lies its only habitat.[2] The springs can be located in Western Wyoming within the Bridger-Teton National Forest at an elevation of 7,800 feet.[3]
