Philodryas baroni, common name Baron's green racer,[1] is a species of mildly venomous snake in the family Colubridae. The species is endemic to South America.


The Latin specific name, baroni, honors Manuel Barón Morlat, who collected the first specimens.[2][3]


Philodryas baroni can reach a total length (including tail) of about 150–180 centimetres (59–71 in).[4] The males are smaller than the females. The length of the tail is about 30% of the total body length. This species is the longest known in the genus Philodryas. The head is small and elongated, with an extension of the rostral scale, forming a small flexible nasal protuberance more developed in males. The coloration of the body is rather variable.[5] Usually it is green, but there are found specimens tending to blue or brown. The pattern can be uniform or with black longitidinal stripes on the back and on the sides, on the anterior third of the body. The ventral area under the black lateral lines can be white or yellowish-white, sometimes with shades of green or blue.[5]


Philodryas baroni is a strictly arboreal snake, with an intense activity during the day. It is generally non-aggressive.[4] If it is frightened, it emits a foul-smelling substance from the cloaca.[4]


P. baroni feeds on small mice, small lizards, and amphibians.


P. baroni is opisthoglyphous, i.e., equipped with rear fangs. It does not seem to have a powerful venom, however caution is required. The observed effects are limited to edema accompanied by slight burning pain and minimal local bleeding.[4][5]

Geographic range[edit]

P. baroni can be found in Argentina, Bolivia, and Paraguay.[1]


P. baroni lives in forests and savannah woodlands.[4]


P. baroni is oviparous.
