Snakes Quiz – Legless Hunters

Snakes are legless reptiles found on every continent except Antarctica. There are over 3,900 species, from tiny thread snakes the size of an earthworm to giant pythons and anacondas that can swallow a deer. All snakes are carnivores.

Without legs, snakes rely on other senses and skills. They smell with their tongues, feel vibrations through their jaws and some sense heat from warm prey. Constrictors squeeze their prey, while venomous snakes inject toxins through hollow or grooved fangs.

Only a small share of snakes are dangerous to people, but snakebite is still a serious health problem in rural parts of Asia and Africa. Snakes also help people by controlling rats and mice, and many are threatened by habitat loss and persecution.
