How do I tell the difference between a young Bullfrog and a young Green Frog?
Juvenile Green Frogs and Bullfrogs should be easily separated by the presence or lack of dorsolateral folds (which are folds of skin, not bony ridges). The dorsolateral folds are the raised lines on a frog’s back. They are present inGreen frogs, but not in Bullfrogs. In addition, female Bullfrogs and Green frogs will have a small tympanum (eardrum) compared to the males. Bullfrog tadpoles regularly take two years before metamorphosis. In some areas it can be three years. Bullfrogs will not breed without calling, but juvenile frogs will disperse from adjacent ponds or rivers. Bullfrogs and Green Frogs will not interbreed.
