Description

Undoubtedly Britain's most well-known amphibian, the common frog is often found in garden ponds (2). They are typically brown or greyish in colour, but some individuals may be yellow or reddish. The flanks are usually yellow, the underside white, and the upper surfaces feature variable blackish markings (5). The large hind legs feature webbed feet; they power strong jumps and an excellent swimming ability, and are covered with dark bands, which provide camouflage (5). Males tend, on average, to be slightly smaller than females, and they can be identified by whitish swellings on the inner digits of the front feet, which support dark pads during the breeding season that allow the male to effectively grasp a female (5).
