Anaxyrus speciosus
The Texas toad (Anaxyrus speciosus) is a medium-sized toad found in the southern United States and northern Mexico. Distinctive for its breeding behavior in temporary pools after heavy rains, it is well-adapted to arid environments. This species is recognized for its "series of explosive trills" call, particularly at night, which attracts females.

About Anaxyrus speciosus
Anaxyrus speciosus: The Texas Toad
The Texas toad (Anaxyrus speciosus) is a species of amphibian native to the southern United States and northern Mexico, notably designated as the Texas State Amphibian in 2009. This medium-sized toad is well-adapted to arid environments, inhabiting dry grasslands, savannahs with scattered mesquite, and open woodlands, often on sandy or frequently inundated soils.
Description and Adaptations
Adult Texas toads range from 52 to 91 mm (2.0 to 3.6 inches) in snout-to-vent length, with females generally being larger than males. Their survival in dry conditions is aided by their ability to dig burrows in soft soil and bury themselves, or to seek refuge in mud cracks, under logs, or in abandoned gopher burrows to prevent desiccation.
Breeding and Ecology
Breeding activity is closely tied to seasonal rainfall. After heavy rains, temporary water pools, ditches, and cattle tanks become vital breeding sites. During these periods, males congregate and emit a distinctive call, described as a "series of explosive trills," particularly at night, to attract females. Eggs are laid in the water, hatching within two days. The tadpole stage lasts between eighteen and sixty days, influenced by water temperature, before metamorphosis into juvenile toads. The Texas toad's diet consists of insects, including beetles, ants, and bugs.
Distribution and Conservation
The Texas toad's range includes Texas, Oklahoma, New Mexico, and northern Mexico. It is considered one of the most common toads in its region and exhibits tolerance to habitat changes, being found in both natural grasslands and cultivated areas. Due to its wide distribution and substantial population, the International Union for Conservation of Nature (IUCN) has assessed the Texas toad as a species of 'least concern,' with no particular threats currently identified.
