Mink Frog

Rana septentrionalis


"The Mink Frog is one of the three green-faced frogs in Vermont and measures 2-23/4 inches long. In Vermont this species generally has dorsolateral ridges. The Mink Frog has dark oval spots oriented along the axis of its legs, unlike the Green Frog and the Bullfrog, which have stripes perpendicular to the axis of their legs. The Mink Frog’s call sounds like horse’s hooves on cobblestones or two sticks being tapped together. Females lay eggs in round masses that can be as much as 3 feet below the surface. The masses are brownish in color and have between 500-4,000 eggs. Tadpoles can spend more than one winter in the water before metamorphosing. The Mink Frog is a northern frog, and Vermont is at the southern tip of its range. They are only found in the north central and northeast portions of Vermont and even there they are unusual.


thanks for the frog photos. You are correct that the first photo is a Mink Frog. It is a first from Williamstown for that species. Could you please tell me what body of water it was in, or perhaps a street address. It is a good find.
