Physical Description

Species Rana septentrionalis

The Mink Frog is a small to medium frog attaining a length of nearly 3 inches. The color on their dorsal surface can be variable, but is generally a green with brown to black mottling. The mottling changes to dark irregular blotches on the upper surfaces of the legs . Like some other species of frogs, the gender of the individual can easily be determined by the size of the tympanum relative to the eye. The male's tympanum will be quite larger than the eye and the female's tympanum will be about the same size or smaller.

Habitat

Mink Frog is highly aquatic and will be found not too far from the water. They can be found in areas where water lilies are abundant. The lilies provide a means of escaping many predators by using the lilies to move out on to the pond .

Typically found at an altitude of 0 to 649 meters (0 to 2,129 feet).[1]

Ecology: Bogs , cold lakes and ponds , inlets and outlets of ponds and lakes; occupies sphagnum mats and emergent vegetation (e.g. , lily pads ) in open water . It hibernates underwater. Eggs and larvae develop in permanent lakes and ponds.[2]

Similar Species

The Mink Frog can be mistaken with the Green Frog which overlaps much of the Mink Frog's range. The Mink Frog, however, gives off a secretion from the skin that has a distinct odor of a mink or rotten onions. The most reliable way to determine which species you are looking at is to look at the webbing on the hind feet, which reaches the last joint of the longest toe in the Mink Frog. On the Green Frog, the webbing barely extends to the second joint of the longest toe. Green frogs always have dorsolateral ridges, these may or may not be present in the Mink Frog. Green frogs also have cross-bands on their legs instead of blotches.
