Due to their remarkable evolutionary adaptations, the species has attracted great interest from researchers in recent years. The frog has evolved a method of surviving being partially frozen in winter. They have developed special chemical reactions in their bodies that allow this.The Wood Frog has developed a unique mechanism that protects it from dying even if it freezes.Click To Tweet
This process prevents total freezing of the water in their cells and bloodstream. As long as no more than 65% of the water in their body freezes, they survive. Absolutely incredible.
Wood Frog Physical Characteristics
This frog may range 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 are somewhat larger in size than the males.
The adult Wood Frog is typically dark brown or varying shades of tan on their upper body. The underside is generally a pale green or yellow. This animal possesses the ability to alter its coloring at will as well, within the aforementioned range of colors.
Any small brownish colored frog seen in the forest is most likely a member of this species. They are the only known species in North America with this physical appearance.
Wood Frog Habitat
The Wood Frog is almost exclusively forest-dwelling by nature. They also primarily breed in woodland vernal pools and freshwater wetlands. When not breeding, they may be in or near moist ravines, upland habitats, or freshwater swamps.
The adult Wood Frog will spend the summer and spring in ravines, bogs, woodlands, or forested swamps. During the fall they will migrate to neighboring uplands. This is where the majority of this species will live out the winter season. They primarily inhabit the upper layer of soil, just beneath layers of leaves.
The amphibian is principally diurnal and rarely emerges at night unless disturbed.
