Philodryas chamissonis, commonly known as the long-tailed snake, is a species of moderately venomous opisthoglyphous (rear-fanged) snake in the family Colubridae. The species is native to South America.[4]


The specific name, chamissonis, is in honor of German botanist and poet Adelbert von Chamisso.[2][5]

Geographic range[edit]

P. chamissonis is endemic to Chile and has a large distribution, from Copiapó to Valdivia.[citation needed]


Usually, P. chamissonis is gray, with black and white longitudinal stripes on the body. It is a medium-sized snake, which usually reaches 1.4 m (4.6 ft) in total length (including tail).[citation needed]

The length of the tail is 25-28.5 % of the total length. There are 8 upper labials, the 4th and 5th entering the eye. The smooth dorsal scales are arranged in 19 rows at midbody. Ventrals 179-225; anal plate divided; subcaudals 100-122.[6]


Philodryas chamissonis lives in a large variety of habitats.


The diet of P. chamissonis is mainly composed of little rodents, insects, and other smaller reptiles.[citation needed]


P. chamissonis is an oviparous reptile.


Because P. chamissonis is rarely found, bites by it are uncommon. However, its bite is painful and causes extensive swelling.[7]
