Snakes are elongated, legless, carnivorous reptiles that belong to the suborder Serpentes. They are found on every continent except Antarctica, and they inhabit a wide range of habitats, from deserts to forests to oceans.

There are over 3,500 known species of snakes, ranging in size from the tiny thread snake, which is only a few inches long, to the massive anaconda, which can grow up to 30 feet in length. Some of the most well-known species include cobras, pythons, vipers, and rattlesnakes.

Snakes are known for their ability to swallow prey whole and for their venomous bites, which can be deadly to humans and other animals. However, not all snakes are venomous, and many species are harmless to humans.

Snakes play an important role in many ecosystems, as they help to control populations of rodents and other small animals. They also serve as prey for many larger predators, including birds of prey and other snakes.

Overall, snakes are fascinating and diverse creatures that have captured the imaginations of people for thousands of years.
