Until recently, birds attributed to rodents, but it turns out that this is a completely independent group of systematic lagomorphs. In rabbits in the upper jaw are two pairs of incisors, and no one, as in rodents. In lagomorphs the left and right next to the molars have only a narrow bridge, while in rodents in its place a solid bone area. Lagomorphs and rodents differ from the composition of the blood.
Dental device of the jaw apparatus and associated birds in the nature of power. The molars have no roots, the relative positions of the upper and lower teeth is such that between them and their protruding parts are formed of free spaces, thus achieving the best treatment for food.Hardness of feed affects the wear of the teeth, which determines the rate of growth, as food takes a bite and bite off the incisors. Rabbits sometimes special grind solid-growth incisors of browse forage.
Rabbits, especially the hare, are perfectly adapted for running. Their muscular hind legs much longer than the front, enabling it to places develop tremendous speed and move the 3-4-meter jumps. Faster than the other hares hare running (55-70 km / h).
Running speed and is ensured by the special structure of the feet. So, hare foot narrow, long and compact, not adapted to run on soft snow and on hard surfaces. Sole pads covered with coarse hair hare. The device allows it to white hare legs move easily through deep soft snow.White hare’s paw with your fingers spread wide so bushy that even the nails are hidden with hair.
