True Frogs of the United States
True frogs have a bony breastbone and horizontal pupils. North American species are large frogs with slim waists, long legs, pointed toes, and extensive webbing on the hind feet. They are excellent jumpers. The adults are truly amphibious, typically living along the edge of the water end entering it daily to catch prey, flee danger, or to mate. They are all voracious carnivores, feeding primarily on insects, spiders, and crustaceans, but readily accepting anything else that can be caught and swallowed.
Mating usually is initiated in the spring with aggregations of males calling in chorus to attract females to the breeding site. The breeding male has swollen forearms and thumbs for clasping the female behind her forelimbs. In the water, female Rana may lay strings or rafts containing up to 20,000 eggs. The eggs hatch within one month, with the tadpoles metamorphosing into frogs 6 to 24 months later.
