Wood Frog Facts
- Firstly, this remarkable species is best known by its common name of the Wood Frog. Most notably, the amphibian has attracted great interest from researchers in recent years.
- All this attention to an otherwise unassuming creature occurs due to its remarkable evolutionary adaptation. But, this adaptation is well worth the attention, for it seems remarkable.
- That’s because this frog has evolved a method of surviving being partially frozen in winter. It has, quite naturally, developed special chemical reactions in its body that allow this.
- Lastly, this process prevents total freezing of the water in its cells and bloodstream. As long as no more than 65% of the water in the body freezes, it survives. Absolutely incredible.
Wood Frog Physical Description
The Wood Frog often ranges in length from about 2-2.8 in (0.8-1.1 cm). The species also exhibits a slight degree of sexual dimorphism. The females grow to a somewhat larger in size than the males.
The adult individual typically appears dark brown or varying shades of tan on the upper body. The underside generally shows a pale green or yellow.
In addition, this animal further possesses the ability to alter its coloring at will as well, within the aforementioned range of colors.

Wood Frog Distribution, Habitat, and Ecology
However, the amphibian is almost exclusively forest-dwelling by nature. It also primarily breeds in woodland vernal pools and freshwater wetlands. When not breeding, it may be in or near moist ravines, upland habitats, or freshwater swamps.
The adult Wood Frog will spend the summer and spring in these and similar habitats. But, during the fall it will migrate to neighboring uplands. This is where the majority of this species will live out the winter season. It also primarily inhabits the upper layer of soil, just beneath layers of leaves.
Finally, the amphibian evolved as principally diurnal and rarely emerges at night unless disturbed.
