"sidewinder" 的定义和意义

What is a "sidewinder"?

A sidewinder is a unique species of venomous snake found in the deserts of North America. It gets its name from its distinctive method of locomotion, in which it moves in a sideways or "sidewinding" motion across the sandy terrain. This adaptation helps the snake navigate the hot desert sands with ease. The sidewinder has a pale coloration that matches its arid environment, providing effective camouflage. It has a triangular-shaped head and vertical pupils, typical of venomous snakes. Sidewinders are known for their ability to survive in extreme temperatures and harsh desert conditions. They primarily feed on small rodents and lizards, using their venom to immobilize and subdue their prey. Although they possess venom, sidewinders are generally non-aggressive and prefer to avoid human encounters.
