Amargosa toad Facts
Amargosa toad is a species of North American amphibian that belongs to the family of true toads. It can be found only in the Oasis Valley in Nevada (USA). Amargosa toad inhabits only area that stretches 10 miles along the Amargosa river and small parts of the nearby upland springs. Number of Amargosa toads in the wild is rapidly dropping due to habitat loss, urbanization of this region, increased number of off-road vehicles, over-grazing and introduction of non-native animal species. Amargosa toad is on the list of endangered species (which means that it can become extinct in the near future).

Unlike other species of toads and frogs, Amargosa toad does not produce croaks. This toad is silent most of the time, except when it is threatened. Only males are able to produce alarm calls (chirps) when predators grab them.
Major predators of Amargosa toads are non-native, introduced species of animals such as bullfrog, crayfish and catfish. These species quickly managed to occupy Amargosa toad's habitat due to plenty of food and lack of natural enemies. Bullfrog, crayfish and catfish eat eggs of Amargosa toads and hunt immature toads.
Mating season of Amargosa toads takes place during the spring. It usually starts in February and lasts until June.
Female produces up to 6.000 eggs arranged in the form of long strings. Eggs are attached to the plants that grow near the streams or shallow pools of water.
Eggs hatch after one or two weeks. Tadpoles transform into young frogs after 4 to 8 weeks, depending on the temperature (higher temperature accelerates development).
Amargosa toad reaches sexual maturity at the age of 2 to 3 years.
Amargosa toad can survive 9 to 12 years in the wild.
