Overview
The Mexican Burrowing Python is a rare, secretive snake found in Mexico and Central America, notable as the only living species in its family, Loxocemidae, which is closely related to the true pythons of the Old World. Its discontinuous distribution and primitive features make it of significant interest to herpetologists studying snake evolution.
It is non-venomous and constricts its prey. Due to its fossorial and nocturnal habits, it is rarely encountered by people and poses no threat to humans.
How to identify it
- Stout, cylindrical body with smooth, glossy scales
- Dark brown to blackish dorsal coloration with an iridescent sheen, often with a paler belly
- Small head not markedly distinct from the neck
- Vestigial pelvic spurs near the tail, a primitive feature shared with pythons and boas
- Adult length typically 1-1.4 m (3.3-4.6 ft)

Found in tropical dry forest, deciduous forest, and lowland habitats along the Pacific coast of Mexico south through Central America. Fossorial, spending much of its time burrowing in loose soil or leaf litter.
Behavior, diet & reproduction
Nocturnal and secretive, rarely seen above ground during the day. Feeds on lizards, small mammals, and reptile eggs, killing prey by constriction. Reproduction is oviparous, with clutches of several eggs laid in underground burrows.
