colorado river toad for sale

In the United States, the Colorado River toad is found in the lower Colorado River and the Gila River catchment areas, in extreme southwestern New Mexico and much of southern Arizona. It is considered possibly extirpated from California.

 In Mexico, the toad is found in the states of Sonora, Sinaloa, and Chihuahua. It lives in both desert and semi-arid areas throughout its range. It is semiaquatic and is often found in streams, near springs, in canals and drainage ditches, and under water troughs.

 The Colorado River toad is known to breed in artificial water bodies (e.g., flood control impoundments, reservoirs) and as a result, the distributions and breeding habitats of these species may have been recently altered in south-central Arizona. It often makes its home in rodent burrows and is nocturnal.

The Colorado River toad is sympatric with the spadefoot toad (Scaphiopus spp.), Great Plains toad (Anaxyrus cognatus), red-spotted toad (Anaxyrus punctatus), and Woodhouse’s toad (Anaxyrus woodhousei). Like many other toads, they are active foragers and feed on invertebrates, lizards, small mammals, and amphibians.

The most active season for toads is May–September, due to greater rainfalls (needed for breeding purposes).

The age of baby colorado river toad individuals in a population at Adobe Dam in Maricopa County, Arizona, ranged from 2 to 4 years; other species of toad have a lifespan of 4 to 5 years.^[9] The taxonomic affinities of I. alvarius remain unclear, but immunologically, it is similarly close to the boreas and valliceps groups.
