American Bullfrog
Description
 3 1/2-8". The largest frog in North America. Green to yellow above with random mottling of darker gray. Large external eardrum; hind feet fully webbed except for last joint of longest toe. No dorsolateral ridges. Belly cream to white, may be mottled with gray.
Voice
Deep-pitched jug o'rum call can be heard for more than a quarter of a mile on quiet mornings.
Breeding
Northern areas, May to July; southern, Febuary to October. Egg masses are attached to submerged vegetation. Tadpoles are large, 4-6 3/4", olive-green, and may take almost 2 years to transform.
Habitat
Aquatic. Prefers ponds, lakes, and slow-moving streams large enough to avoid crowding and with sufficient vegetation to provide easy cove.
Subspecies
Other
Nocturnal. Less aquatic then the Pig Frog, it is usually found on the bank at water's edge. When frightened, it will as soon flee into nearby vegetation as to take to the water. Large specimens have been known to catch and swallow small birds and young snakes; its usual diet includes insects, crayfish, other frogs, and minnows. Attempts to commercially harvest frogs' legs have prompted many introductions of the Bullfrog outside its natural range.
