Ring-Headed Dwarf Snake

The ring-headed dwarf snake is a pencil-thin species that grows to a maximum length of 60 cm (24 in) but most adults are considerably smaller than this. The skin is smooth and the edges of the scales are slightly darker than the centres. The upper surface of the body is a uniform yellowish-brown, greyish-brown or reddish-brown colour and the underparts are glossy white. The top of the head has a large black blotch inside which are either two whitish spots or a pale W-shaped mark. Round the neck is a crescent-shaped band of dark blotches separated from the head by a pale band.

The ring-headed dwarf snake is native to the Greek Mediterranean islands of Lesbos, Chios, Samos, Fournoi, Kasos, Karpathos, Kalymnos, Leros, Symi and Megisti and most of Turkey. Its range extends eastwards into the Caucasus Mountains, eastern Georgia, Armenia and Azerbaijan. Its natural habitats are dry shrubby vegetation, cultivated fields, fallow areas and dry open woodland.

During the day the ring-headed dwarf snake shelters under stones or in crevices, and several snakes may share the same hiding place. It emerges at twilight to hunt for spiders, insects, centipedes, scorpions and small lizards. Breeding takes place in summer when the female lays a clutch of three to eight relatively large eggs. The hatchlings are up to about 12 cm (4.7 in) long.
