Definition
The term "genus Cerastes" refers to a group of small, venomous vipers commonly known as horned vipers. These snakes are native to the deserts and semi-deserts of North Africa and the Middle East. They are characterized by the presence of horn-like scales above their eyes. The horn-like scales are thought to provide shade or prevent sand from entering their eyes. Think of 'Cerastes' as a specialized line of desert-adapted snakes. They're like the SUVs of the snake world, built for harsh conditions.
