Taxonomy
Woodhouse's toad was first described in 1854 by the French herpetologist Charles Frédéric Girard. He gave it the name Bufo woodhousii in honor of the American physician and naturalist Samuel Washington Woodhouse.[2] The large genus Bufo was split by Frost et al. in 2006, with the North American species being included in the genus Anaxyrus and this toad becoming A. woodhousii.[3][4] There are three recognised subspecies:[5]
- Rocky Mountain toad –
- East Texas toad – Anaxyrus woodhousii velatus (Bragg and Sanders, 1951)[7]
- Southwestern Woodhouse's toad – Anaxyrus woodhousii australis (Shannon & Lowe, 1955)[8]

Description
Woodhouse's toad is a robust amphibian and can grow to a maximum snout-vent length of 127 mm (5 in). The head has prominent cranial crests in front of and in between the eyes. The parotoid glands are long and large. The dorsal surface of this toad is grayish-brown or yellowish-brown and it is speckled with small dark spots. There is a narrow pale line running along the spine. The belly is rather paler and is usually unspotted. The male has a single vocal sac on his throat. His call resembles the bleat of a sheep and lasts from one to three seconds.[9][10]
Distribution and habitat
Woodhouse's toad is found in North America at altitudes of up to 2,500 metres (8,200 ft). Its range extends from Mexico in the south to

Status
Woodhouse's toad has a very wide range and presumed large total population. It is able to live in a number of types of habitat and can tolerate some modification to its habitat. The population seems steady and no particular threats have been identified so the
