Question:
How can I tell the difference between a Male Northern Leopard Frog, and a female Northern Leopard Frog?

Replies:
It is not easy! Males are a little smaller than females and have stouter front legs with enlarged "thumbs." The vocal sac or loose skin around the vocal sac of the male may be visible at the edge of the throat during breeding season.
