Mountain yellow-legged frog Facts
Mountain yellow-legged frog belongs to the group of true frogs. It can be found in California (Sierra Nevada mountain range). Mountain yellow-legged frog inhabits areas near the streams, rivers, lakes and ponds on the altitude of 1.221 to 7.557 feet. Number of mountain yellow-legged frogs has been drastically reduced in the last couple of decades due to habitat destruction, fungal diseases, climate changes, pollution of the air and introduction of non-native species of fish. Researchers believe that wild population of mountain yellow-legged frogs consists of 150 to 200 animals. Captive breeding of mountain yellow-legged frogs is currently the only way to prevent complete extinction of these animals from the wild.

Mating season of mountain yellow-legged frogs takes place from April to July. Males produce croaking and clicking sounds to attract females.
Female lays 40 to 300 eggs on the rocks, gravel or aquatic plants. Eggs hatch after 18 to 20 days at the temperature of 13 degrees of Celsius. Tadpoles transform into young frogs (process known as metamorphosis) after couple of months or after 2 to 4 years, depending on temperature. Mountain yellow-legged frogs reach sexual maturity at the age of 2 years (when they reach length of 1.73 to 1.97 inches).
Mountain yellow-legged frog can survive 14 years in the wild.
