Family : PYTHONIDAE
Species : Morelia viridis
Maximum Size : 1.5 m The Green Tree Python is
one of Papua New Guinea's most well known of snake species. It can be found
in a variety of habitats including dry forest, swamp forest and cultivated
areas.
The adult is unmistakable : the dorsal surface is bright green, or sometimes
bluish, and the ventral surface pale yellow or white. A pale vertebral is
generally seen. Juveniles are mostly bright yellow throughout, but in some
areas may be dorsally red, orange or green. The body is muscular, and the
head is short. The eyes are large with a vertical pupil, and the
heat-sensing pits, with which the snake is able to detect infra-red heat
from warm-blooded prey, are easily visible on the lower lip. As in other
pythons, the head scales are numerous and finely granular.
Green Tree Pythons are not
exclusively tree-dwellers : as shown in these images they are also quite at
home on the ground. They are most likely to rest, however, amongst trees.
Their diet is varied and includes lizards and small mammals.
The species is widely distributed in PNG, to
elevations of 2000m. Its range also extends to the western half of New
Guinea, nearby Indonesian islands, and parts of Australia's Cape York
Peninsula.

night in the middle of a rough road, adjacent to a freshwater swamp
forest next to Lake Kutubu (elevation 835m), Southern Highlands Province,
PNG.

pits lining the lower lip.
