Spilotes pullatus, commonly known as the Caninana or Tiger Rat Snake, is a large, non-venomous snake native to Central and South America. It is known for its striking black and yellow banded pattern, which aids in camouflage. This species thrives in tropical rainforests and is an adept climber, often seen hunting for birds and small mammals.

Spilotes pullatus, commonly known as the caninana or black-and-yellow ratsnake, is native to Central and South America. Its geographical distribution includes countries such as Mexico, Belize, Honduras, Nicaragua, Costa Rica, Panama, Colombia, Venezuela, Guyana, Suriname, French Guiana, Brazil, Ecuador, Peru, Bolivia, and Paraguay.

The species typically inhabits tropical rainforests, tropical and subtropical moist broadleaf forests, and sometimes dry forests. It is adaptable to various altitudes but is predominantly found at lower elevations. The environmental conditions in these habitats include warm temperatures, high humidity, and dense vegetation.

Spilotes pullatus is an arboreal snake, meaning it is well adapted to living in trees. It plays a vital role in the ecosystem as both a predator and prey. It primarily feeds on birds, small mammals, and occasionally lizards and amphibians, thus helping control these populations. Its presence in the canopy and forest floor layers allows it to contribute to the ecological balance within its native habitat.
