Mexican Spadefoot (Spea multiplicata)
Similar in habit to Couch’s spadefoot, the Mexican spadefoot is active during the summer rainy season. They are brownish-gray in color with scattered dark blotches and red bumps. When handled, they emit a skin secretion with a peanut-like odor which may cause the handler’s eyes and nose to run. The call of the Mexican spadefoot has been described as the sound a fingernail makes when dragged along the teeth of a comb.
Length: 1 ½ - 2 ½ in. (3.8 - 6.3 cm)
