Description

Species in the genus ''Coronella'' are relatively small snakes, rarely growing to more than in total length (including tail). The head is only slightly distinct from the neck, and the pupil is round. The teeth of the upper jaw increase in size towards the rear of the mouth. The body is almost cylindrical and covered with smooth scales. The subcaudals are paired.

Behavior

''Coronella'' species are terrestrial and rather secretive, spending much of their time under cover.

Feeding

The diet of snakes of the genus ''Coronella'' is made up mainly of lizards and the young of other snakes, as well as small rodents, especially young rodents still in the nest. They have often been described as constrictors, although there is no good evidence for this. Street (1979) notes that prey is held firmly in its coils, but only for the purpose of restraint rather than to kill it.Street D (1979). ''The Reptiles of Northern and Central Europe''. London: B.T. Batsford Ltd. 268 pp. .

Geographic range

Species in the genus ''Coronella'' are found in Europe, North Africa and West Asia.
