Atractaspis engdahli — a venomous snake from East Africa. It spends almost its entire life in the soil and uses long fangs to hunt in tight burrows.
Atractaspis engdahli is distinguished by its long fangs and its ability to deliver a sideways strike in narrow passages. It helps regulate the number of small vertebrates in the soil of African savannas.
