A Mink Frog [Lithobates septentrionalis – Rana septentrionalis] varies in colour from green to brown often having both colours. While this frog is often mistaken for a Green Frog, the Mink Frog has smaller dorsolateral folds if any at all. This species has large tympani and slightly upturned eyes. There is no banding on the legs and the webbing on the hind foot is more developed. The webbing on the back feet reaches the last joint of the longest toe. The Mink Frog releases a foul smell similar to rotting onions when handled.
If you are not sure what kind of frog you have found, have a sniff, Mink frog's have a pungent, musky odour, like that of a mink.
Similar species - The Mink Frog and the Green Frog are almost identical in appearance. Both come in a variety of colours. A Green Frog will have a white belly with darker lines or spots and sometimes a yellowish tinge. There will be dark banding on the hind limbs of a Green Frog.
