Summary ⁶

The pickerel frog (Rana palustris) is a small North American frog, characterized by the appearance of seemingly "hand-drawn" squares on its dorsal surface.

Description ⁷

It usually has a snout-vent length between 60 and 70 mm. It is smooth-skinned, with dark brown or black dorsal blotches which are often arranged in two regular rows and which usually are squarish or rectangular. It is gray or tan in color, with a bright yellow wash on the concealed surfaces of the hind legs and belly. The glandular, yellowish dorsolateral fold is roughly half the width of a dorsal blotch in large-spotted individuals and more than half in small-spotted individuals.
