Conservation
IUCN Red List status is Least Concern. Main threats include habitat loss, fragmentation, and mortality from vehicular traffic on roads.
Physical Description
Features a patterned dorsal surface with dark blotches or saddles (grey, brown, or black) over a lighter grey or tan background. The head is relatively distinct from the neck, and the eyes feature round pupils. Scales are weakly keeled, and the body can appear somewhat loaf-shaped in cross-section.
Size & Dimensions
The specimen shown is a juvenile, approximately 25 to 35 cm in length. Adults typically range from 100 to 180 cm, with exceptionally large specimens exceeding 200 cm.
Habitat
Found in a wide variety of habitats including deciduous forests, rocky wooded hillsides, agricultural fields, and suburban areas. Prefers areas with abundant cover and vertical climbing opportunities, ranging from sea level to over 1,000 meters elevation.
Diet & Feeding
Juveniles primarily feed on small lizards, frogs, and small mice. Adults consume rodents, bats, birds, and bird eggs. They are agile climbers and employ constriction to subdue their prey.
Reproduction
Oviparous species. Females typically lay clutches of 12 to 20 eggs in mid-summer (June or July) inside rotting logs, leaf litter, or loose soil, where they incubate for about two months before hatching.
Conservation Status
IUCN Red List status is Least Concern. Main threats include habitat loss, fragmentation, and mortality from vehicular traffic on roads.
Cultural Significance
Highly beneficial ecologically for controlling rodent populations around agricultural and residential areas. Often kept as pets due to their adaptable nature and generally calm demeanor when mature.
Notable Features
Remarkable climbing ability, capable of scaling vertical tree bark and rough brick walls with ease. Juveniles display particularly high-contrast patterning that helps camouflage them among leaf litter.
