Rana
sylvatica - Wood Frog Picture: Coming Soon
Size: 1.25" - 3" Approx.
Description: Most of the time the Wood Frogs are dark brown or tan, but there are some indications that they can be black to red or pinkish color.
Habitat: Forest species and most commonly found under logs, rocks, leaf litter and stones.
Life History: Eggs: .25-.5" with a black embryo in masses of 500-3000 eggs Larvae: Hatch within 28 days at +/- .25" and will feed off symbiotic algae that grows on egg masses. Usually by June the larvae will have grown legs and undergo metamorphosis before pool dries.
Cool things: Wood frogs are freeze tolerant species. Meaning they basically have anti-freeze in there blood that allows them to sustain freezing temperatures. As much as 45% of the frog can freeze. When its time to breed, male Wood Frog's develop enlarged thumbs and forelimbs to help hold the female.
Identification: Typically I look for the black "mask" behind its eyes. There is also a black line from the eye to the mouth. Males have convex webbing and females have concave webbing. There egg mass can be large with a blue tint to them, containing 500-3000 eggs. These masses retain heat to promote development.
Diet: Spiders, worms, slugs etc...
