“ The snout is quite short and on the back there are long oval shaped parotoid glands. There is a long cream colored stripe down its back, which can be very faint as well. They have dark red spots which are outlined by an even darker color. Like the spadefoot toad it survives the driest of weather by burrowing underground. On each hind foot is a hard rubbery knob which helps it dig quickly when needed. They generally emerge after heavy rainfall. ”

“ The toads have a bump between the eyes, which gives the head a distinctive shape. Spadefoots have bumpy skin but do not look as “warty” as Western Toads. A spadefoot sitting still on the ground looks like a large pebble, so they can go undetected by a predator. Adults range from 4 to 6.5 centimeters from nose to end. ”

“ As a ‘true frog’, the leopard frog lives where there is a constant supply of water. This frog has raised dorosolateral folds which go down the entire back and a light stripe on the upper jaw. They are primarily nocturnal. The webbing on the feet does not extend to the end of the toes.
