Скачать или смотреть Pool Frog | The pool frog has a wide range across much of Europe.

The heaviest toll appears to have fallen on the native pool frog populations of Britain. The UK frogs went completely extinct in the mid-1990s and had to be reintroduced from Sweden. The culprit for this demise appears to be pollution and habitat loss to which these frogs are particularly vulnerable. As the name suggests, this species has an affinity for small pools of water, and when the weather turns frosty, it hibernates for the winter.
One of the more interesting facts is that the pool frog has the ability to interbreed with the closely related marsh frog to produce a hybridized animal called the European edible frog. These male and female edible frogs can in turn produce viable offspring with the pool and marsh frogs, but if they try to mate with each other, then only infertile offspring will tend to result. The edible frog has green and yellow colorations with black stripes and splotches over its body.
Like most other amphibians, the pool frog has highly porous skin that can absorb oxygen and exchange gasses. In other words, it can quite literally breathe through its skin. This means it needs to be constantly moist to exchange gasses. However, the porous skin is also very susceptible to pollution.
The pool frog’s camouflage colors allow it to blend in with the environment and evade hungry predators.
Like many other species of frog, the pool frog has a pointed head, long legs, webbed hind feet, and horizontal pupils, but the easiest way to identify them is their color. They have a brown or green body color with big dark blotches, a white stomach, and a light yellow or green stripe running straight along the back. The exact arrangement of colors and patterns vary between populations and even individuals.
The pool frog is a very small creature that measures not much more than 2.3 to 3 inches in size. Males are slightly smaller than females and have two big inflatable vocal sacs on the side of their head. These sacs serve as a means to amplify the male’s mating call when it is time to breed.
