The common toad is a drowsy-looking amphibian of brown or olive-brown color. The underside is typically white or gray, and the eye, which has a horizontal pupil, is copper in color. Adult male toads grow to a length of 8 cm, whereas the larger females can be up to 13 cm long. Common toads secrete a foul-tasting, irritant chemical [bufagin] from their warty skin, and this toxin deters most predators from eating them.
The common toad in my photograph is fairly large. Thus, I assume it is a female.
