The fastest among turtles is the Skin Tortoise (Dermochelys coriacea). It reaches a speed of movement in water – 35 km / h. The speed of movement overland is no more than 15 km / h. Its mass can reach up to 600 kg, the body length is from 1.8 to 2.1 m, and the width at the level of the front fins is 2.1 m. The male, found dead on the shore in Harlek, United Kingdom, in 1988, had a common length 2.91 m, width 2.77 m and weight 961.1 kg.
Turtles are wise and intelligent animals. Such a statement was due to the fact that turtles live for a long time. Accordingly, in the human eye, animals look wise, as their age helps to accumulate knowledge. But even when testing, the turtles show fairly good results.
So, they can learn to find a way out of the labyrinth and place for feeding, surpassing in testing snakes and lizards. Also the results of the next test are curious. The tortoise moved along the rail behind the slowly moving feeder. Suddenly she disappeared behind the screen. The animal continued to move in the same direction, discovering as a result its food on the other side of the screen.
The solution of such a task turned out to be beyond the power of some birds, by default more intelligent. There are cases when in the deserts the turtles, after rains, construct themselves swimming pools, in which water can remain for a long time. In North America, cunning turtles have learned to lay eggs in the nests of alligators, where predators operate much less frequently.
