Javelin Sand Boa (Eryx jaculus)

…is a species of Old World sand boa (Erycinae) that is native to Eastern Europe, the Middle East, and parts of Africa. Like other sand boas Eryx jaculus spends most of its time burying in the sand with only its eyes exposed, waiting for potential prey to approach. E. jaculus feeds mainly on rodents, but is known to feed on other small animals as well.

Kenyan Sand Boa - Eryx colubrinus

The sand boas are a group of generally small boids related to the rosy and rubber boas of North America, and together they make up the group (subfamily) called the Erycinae boas.

Also named East African Sand Boa, Eryx colubrinus (Boidae), is in build a typical sand boa, but colored orange or yellow with chocolate-brown to black splotches. The belly is white or cream. In the wild, this species ranges through Egypt, Sudan, Ethiopia, Kenya, Libya, Chad, Niger, Yemen, Tanzania, and Somalia.

They eat small rodents and lizards, which they catch by lying in wait nearly buried in the dirt or sand until a potential meal walks by. Relatively small prey are grasped very quickly and suffocated not by constriction but by pulling them under the sand.

Rubber Boa (Charina bottae)

Also sometimes known as the Coastal Rubber Boa or the Northern Rubber Boa, the rubber boa is a species of boa (Boidae) that is native to the Western United States and Southwestern Canada. Rubber boas are known to inhabit a wide variety of habitats ranging from grassland, meadows and chaparral to deciduous and conifer forests, to high alpine settings. Rubber boas are notably docile and when threatened will release a potent musk instead of biting. Rubber boas are primarily nocturnal, but are also though to likely be crepuscular as well. Like other boas C. bottae is a predator and will feed on young mammals, eggs, and birds.
