Another early spring frog,
the wood frog measures from 2 to 2 3/4 inches (5-7 cm.) long.
The presence of a "robber's mask" makes this an easy species to
identify. The body color is generally light tan to dark brown,
with a series of darker brown lines along the dorsolateral folds
(the raised bumps between the eyes and the hind legs).
Found in
most of Minnesota except the southwest corner, wood frogs prefer
woods and forests and require marshes and small ponds for breeding.
