Description

Grows to an average length of 50-70 cm, with a maximum of 98.5 cm.[2]

Geographic range

The Grecian islands of the Cyclades Archipelago in the Aegean Sea: Milos and the three smaller, adjacent islands of Siphnos, Kimolos and Poliaigos.[1][2] The type locality is given as "Insel Milos."[1]

Conservation status

This species is classified as Endangered (EN) according to the IUCN Red List of Threatened Species with the following criteria: B1ab(iii,v) (v3.1, 2001).[5] This indicates that the extent of its occurrence within its geographic range is estimated to be less than 5,000 km², that its populations are severely fragmented or known to exist at no more than five locations. Furthermore, a continuing decline is observed, inferred or projected in the area, extent and/or quality of habitat, as well as the number of mature individuals.[6]

So listed because its extent of occurrence is, in fact, not much greater than 100 km² -- it is known from only four small islands. There is continuing decline in the extent and quality of its habitat, and it is experiencing a decline in the number of mature individuals due to persecution and over-collecting. Year assessed: 2005.[5]

It is also listed as strictly protected (Appendix II) under the Berne Convention.[7]
