This petite amphibian, measuring only 1.5-2.5 inches, is adorned with a captivating dull green or gray color and contrasted by dark brown blotches. Though small in stature, these colorful creatures demonstrate impressive adaptability to the arid environments of their highly specialized habitat in Central Nevada.
Their residence of choice – spring-fed marshes and wet meadows – contributes to their highly specialized diet of small invertebrates and insects. Nestling within the heart of the United States – only found in the Railroad Valley of Nevada – their breeding practices are quite distinctive. Males emit low-pitched, slow trill calls to woo their mates, ultimately laying their eggs in strings amidst a haven of shallow, warm pools.
Despite their admirable adaptability to their arid habitats, the conservation status of these alluring amphibians is vulnerable. The uniqueness and isolation of their Nevada haven make them an invaluable treasure of North America’s ecological diversity.
