About the Aesculapian Snake

The Aesculapian snake (Zamenis longissimus, previously Elaphe longissima) is a species of non-venomous constrictor snake native to Europe, a member of the subfamily Colubrinae of the family Colubridae. Growing up to 2 metres (6.6 ft) in length, it is among the largest European snakes, similar in size to the four-lined snake (Elaphe quatuorlineata) and the Montpellier snake (Malpolon monspessulanus). The Aesculapian snake has been of cultural and historical significance for its role in ancient Greek, Roman, and Illyrian mythology and derived symbolism.

Zamenis longissimus hatches at around 30 cm (11.8 in). Adults are usually from 110 cm (43.3 in) to 160 cm (63 in) in total length (tail included), but can grow to 200 cm (79 in), with the record size being 225 cm (7.38 ft). Expected body mass in adult Aesculapian snakes is from 350 to 890 g (0.77 to 1.96 lb). It is dark, long, slender, and typically bronzy in colour, with smooth scales that give it a metallic sheen.

Juveniles can easily be confused with juvenile grass snakes (Natrix natrix) and barred grass snakes (Natrix helvetica), because juvenile Aesculapians also have a yellow collar on the neck that may persist... Wikipedia →
