Rana catesbeiana


The bullfrog is the largest frog in the U.S., ranging in length from 3.5 - 8 in (9 - 20 cm.). Coloration is normally plain green above, or a netlike pattern of gray or brown on a green background. The venter is whitish and often has grey mottling with a yellow wash, which is evident on the throats of adult males. In the southeastern part of the bullfrog's range, coloration can be a heavy pattern of dark grey, brown, or black above, and thick mottling below. They have no dorsolateral ridges, distinguishing it from the similar green/bronze frog (Rana clamitans). The bullfrog closely-resembles the pig frog (Rana grylio), but bullfrogs have a less-pointed snout and less-extensive webbing between the toes (webbing does not reach the end of the toe). see reference link


The second pic is a Bullfrog tadpole seen in the same pond on the same day. There were a LOT of them and they are very large.
