Gray tree frog for sale

They also range into Canada in the provinces of Quebec, Ontario, and Manitoba, with an isolated population in New Brunswick.

As the scientific name implies, gray treefrogs are variable in color. This ability to vary their color provides them with the ability to camouflage themselves from gray to green or brown, depending on the environment around them. D. versicolor can change from nearly black to nearly white.

They change color at a slower rate than a chameleon. A unique aspect of the appearance of gray treefrogs is that its legs feature a dark band-like pattern which then contrast sharply with the black-marked bright yellow or orange under the sides of its legs and arms. Dead frogs and ones in unnatural surroundings are predominantly gray.

The female does not call; however, the male does call. Female frogs are usually larger than their male counterparts. They are relatively small compared to other North American frog species, typically attaining no more than 1.5 to 2 in (3.8 to 5.1 cm) in length. Their skin has a lumpy texture to it, giving them a warty appearance.

This species is virtually indistinguishable from Cope’s frog, the only readily noticeable difference being that Cope’s Gray treefrog has a shorter, faster call. This varies depending on the temperature, however, as the call rates of both gray treefrogs are temperature dependent.

At lower temperatures, Cope’s gray treefrog can have a call rate approximating that of the frog. This difference in calling can be heard, but it is best quantified by counting the number of pulses per second in their whistled trills. At usual temperatures, the frog has a pulse rate of 16 to 34 pulses per second, while Cope’s frog has a pulse rate of 34 to 60 pulses per second.

Even though there is potential for overlap, because of the temperature dependence of the pulse frequency the two species are easily distinguished where they occur together. At a given temperature, the pulse frequency for the treefrog is approximately one-half that of Cope’s frog.
