The Wood Frog (Rana sylvatica) has a broad distribution over North America, stretching from the southern Appalachians to the boreal forest with several notable disjunct populations including lowland eastern North Carolina. This frog has garnered attention by biologist over the last century due to its freeze tolerance, relatively great degree of terrestrialism, interesting habitat associations, and relatively long-range movements. The wood frog is the state amphibian of New York. Similar to...
The Common Frog (Rana temporaria), known also as the European Common Frog or the European Common Brown Frog, is located throughout much of Europe as far north as well north of the Arctic Circle in Scandinavia and as far east as the Urals, except for the majority of Iberia, southern Italy, and the southern Balkans. The farthest west it can be found is Ireland, where it has long been considered erroneously to be an entirely introduced species. These frogs measure about 2.4 to 3.5 inches and...
The Mountain Yellow-Legged Frog (Rana muscosa) is a true frog native to California. They can be found in mountain creeks and lakes, meadow streams, isolated pools, and lake borders. They are usually found near steep-gradient streams of a chaparral belt or other water sources around 1,200 to 7,750 feet above sea level. The Southern Mountain Yellow-legged Frog is endangered and the Sierra Mountain Yellow-legged Frog is threatened. This is a small frog, measuring about 5 to 7.5 centimeters....
The Columbia Spotted Frog (Rana luteiventris) is a North American species of frog. It’s green to brown in coloration with spots on the dorsal surface. The belly and the upper lip are white. Individuals can be distinguished from other Rana species by their shorter back legs, upturned eyes, and narrow snout. Since they spend the majority of their time within the water, they also have more webbing in their hind feet than similar species. Although they are not threatened, the animal has been...
The Japanese Brown Frog (Rana japonica) is a species of frog belonging to the Ranidae family. It is native to Japan. Its natural habitats include temperate grasslands, rivers, swamps, irrigated land, and seasonally flooded agricultural land. Some defining characteristics include a slender and reddish brown body with a long and narrow head. The average snout to vent length is 48 millimeters for males.
