Boelen's pythons are some of the least-understood pythons. They have been found only in mid-mountain forests in Papua New Guinea. Papua New Guinea has over 100 species of snakes, and many can be found only on the island. Boelen’s pythons seem to prefer areas with high humidity and low light levels. Although they live mainly on the forest floor, they are agile snakes. It is likely they climb trees and are at least partially arboreal.

Young and Family

A female will lay a large clutch with at least 14 eggs. At hatching, the Boelen's pythons are reddish in color. As they grow, they develop their adult coloration. As adults, their tops are black and their underbellies are white-yellow.

Historic Hill is a lovely stroll through one of the oldest parts of the Saint Louis Zoo. From the 1904 World’s Fair Flight Cage to the Spanish architectural flavor of the 1920s in the Bird House, Primate House and Herpetarium to the finishing touches of our thoroughly modern exhibits, this area of the Zoo has a unique ambiance and a nostalgic history that make it a great destination.
