Smooth or smooth snakes ( Coronella ) include three types, two of which occur in Europe. Even if they hiss in danger, can go over to fake attacks and bite when grasped, they are harmless snakes. Smooth snakes or smooth snakes inhabit dry, stony and well-sunlit biotopes, prefer to feed on lizards and rarely grow longer than 80 centimeters.
features
Features of this genus are the small head, slightly separated from the neck, round pupils and the smooth, shiny body scales that give it its name. An important distinguishing feature from the otters are the large, smooth scales.
behavior
These animals show activity both during the day and at night. Often they specialize in their diet on lizards, which are killed by being entangled and strangled. In case of danger, they flatten their heads, which makes them appear larger, and they make sibilants. It is also not uncommon for bogus attacks to be carried out.
