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.

[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] The primary threats to the fish were once overfishing, pollution, and habitat degradation.

[5] Today the species could see issues in a lower water table, invasive species, illegal fishing/capturing, and various causes of further habitat degradation, but the Forest Service continues to monitor the population and is actively protecting the habitat.
