About the Kenyan Sand Boa

The Kenyan sand boa is a heavy-looking reptile with a blunt head, small eyes, and a thick, short body. Its belly is white or cream colored and its back has orange or yellow coloration with dark brown splotches. The tail is very short and tapers quickly to a dull point and can’t be coiled. The boa’s eyes and nostrils are placed on the head so that they remain free of debris when the snake’s body is hidden below the sand

Habitat

Found in East Africa, Egypt south to Tanzania, and southwest Somalia west to Kenya in semi-arid desert regions, scrub savannahs, and rock outcroppings.

Behavior

The Kenyan sand boa spends most of its life buried in the sand where it is invisible. It will also hide under stones and in the burrows of other animals.

Because of the desert heat, it is not active during the midday heat, only emerging early in the morning and in the evening to search for food. It seizes its prey and suffocates it between the coils of its body, only relaxing its embrace when the animal stops breathing. It then swallows its victim whole, without chewing, in the same way as other snakes. This snake is considered a docile species and rarely strikes or bites. In fact when threatened, it buries itself quickly and carefully in soft ground, usually sand.


Diet

Sand boas eat mainly rodents, such as mole rats and lizards. Their main predator is the desert monitor lizard.
