Amphibians and reptiles seek refuge

Many of our fish do not sleep in the winter, though in cold water, they become less mobile and almost all are no longer there. Beginning of hibernation of amphibians and reptiles have the same with the first heavy frost and the massive fall of the leaves. Early autumn, while frequent warm days, they sometimes still occur. In the second half of September will be born cubs have no legs (and therefore similar to a snake) lizards veretenitsy. This is a completely harmless substance, in some places is considered very toxic and are striving to destroy, although there were no poisonous teeth veretenitsy not. She even beneficial, eating insects. Snakes hibernate mostly in October. Already among them the most cold-hardy: it happens, he crawls out on warm days even in November. Snakes spend the winter as the adder, in ground burrows or in the forest near the roots. Vipers, curled into a ball the whole, found wintering in the hollows of decayed trees. Often they spend the winter, gathered dozens deep in burrows or hollows under tree roots. Adult lizards usually spend the winter in their burrows, crawling into them more deeply. Young lizards are hiding in the winter under the moss, climb under the roots of trees, empty burrows and other secluded place. The farther to the north, the longer the dormancy of reptiles. Under the Archangel hibernation lizard stretches of at least 8 months. In the middle band is much smaller, but still about six months. Toads go for the winter in mid or late October, depending on the weather. They climb into the hole, which themselves are dug in the ground. They are found in pits under the tree roots, often several at once. Earlier than other frogs in hibernation go green: pond (Rana esculenta L.) and lake (R. ridibunda Pall.). Usually, even before October, they descend to the bottom of ponds and there, buried in mud, lie motionless until about mid-May. Less sensitive to cold grass (Rana tempo-gagіa L.), moor (Rana terrestris Andr., Arvalis Nilss.) Frogs hibernate and wake up later than ever before. In one of the warm springs observed cessation of hibernation in common frog on March 21, and whichever is later marked by April 23.
