* Distinguished by a black patch that extends behind the eye, over the
'ear', to the base of the front limb.
* Skin smooth, with no warts. Back and sides colored varying shades of
* Toes pointed, legs long and slender.
* Male darker, female bigger.
* Length: 2 2 3/5".
* Habitat: Woodlands in the summer, under stones and stumps in winter,
wood ponds in breeding season.
* Range: Northern, eastern, and central United States, southeastern and
* Voice: A hoarse clacking, resembling the quack of a duck.
* Behavior: Mates in April in the north, earlier in the south. Feeds
on insects. In spring, the female lays black and white eggs, in spherical
underwater clusters coated in jelly. The pink and bronze tadpoles hatch
in 4 to 24 days, developing into adults in four years.
* Wood frogs have perfected cryogenic freezing long before humans...in
the winter, as much as 35 to 45 percent of the frog's body may turn
to ice. Ice crystals form beneath the skin and become interspersed
among the body's skeletal muscles. During the freeze, the frog's breathing,
blood flow, and heartbeat cease. Freezing is made possible by specialized
proteins and glucose, which prevent intracellular freezing and dehydration.
* Wood frogs are masters of camouflage - they can change from
dark to light to match with their surroundings within an hour.
