American toad

Medium-sized toad usually ranging in size from 5–9 cm (2.0–3.5 in);[7] record 11.1 centimetres (4.4 in).[8] The colour and pattern is somewhat variable. Skin colour can change depending on humidity, stress, and temperature. Colour changes range from yellow to brown to black. Their breeding habits are very similar to Bufo fowleri. The call or voice of a breeding male is a high trill, lasting 6–30 seconds,[8] similar to a ringing telephone.
