Threatened species of colorado river toad for sale

Due to the rising popularity in collecting this toad, compounded with other threats such as motorists running over them, and predators such as raccoons eating them, U.S. states such as New Mexico have listed them as “threatened” and that collecting I. alvarius is unlawful in those states.

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 I. alvarius 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. The taxonomic affinities of I. alvarius remain unclear, but immunologically, it is similarly close to the boreas and valliceps groups.

The breeding season starts in July, when the rainy season begins, and can last up to August. Normally, 1–3 days after the rain is when toads begin to lay eggs in ponds, slow-moving streams, temporary pools or man-made structures that hold water. Eggs are 1.6 mm in diameter, 5–7 mm apart, and encased in a long single tube of jelly with a loose but distinct outline. The female toad can lay up to 8,000 eggs.
