Overview
The sand boa is a short, thick-bodied member of the boa family adapted for a fossorial lifestyle, spending most of its time buried in loose sand or soil with only its eyes exposed. Its blunt tail, similar in shape to its head, is thought to serve as a decoy to confuse predators.
Despite its small size and harmless nature, it is sometimes mistaken for a viper due to its stocky build and irregular blotched pattern.
How to identify it
- Short, thick body tapering to a blunt tail resembling the head
- Rough, irregular blotched pattern in shades of brown, tan, and reddish-brown
- Small eyes positioned high on the head for a burrowing lifestyle
- Rounded head not clearly distinct from the neck
- Distinguished from vipers by round pupils and lack of a triangular head

Found in dry scrubland, sandy plains, agricultural areas, and rocky terrain across the Indian subcontinent and Sri Lanka. Spends most of its time underground or buried in loose substrate.
Behavior, diet & reproduction
Primarily nocturnal, emerging at night to ambush prey from just beneath the sand's surface. Feeds on small mammals, lizards, and occasionally birds. Live-bearing, producing litters of small young.
