|There are twenty-one species of frogs and
toads (order Anura), represented by five families currently found in
Illinois. Because of their often quiet behaviors they are most
obvious to us during their breeding seasons when males produce their
mating calls. Females do not vocalize. There's no temptation to confuse
a frog with a salamander or lizard, but sometimes frogs and toads can be
confused. Toads have a thicker skin and can endure dryer conditions than
frogs, but they both lack scales and have skins modified to aid in
There are 12 species of anurans, representing three families, found in Hamilton County. Adult frogs and toads are usually identified by the amount of webbing between their toes, the presence of parotoid glands, skin folds on their backs and whether or not there are toe pads. Mouth structures are used to identify tadpoles and it is usually easier to allow the tadpoles to mature to adults than it is to key them out to species.
Living specimens should be kept cool and damp. Tap water and metal salts can kill them.
The following list is composed of species which have been found in Hamilton County or in the Saline River watershed.
