Snakes are elongated, legless reptiles belonging to the suborder Serpentes. They are found on every continent except Antarctica and inhabit a variety of environments, including forests, deserts, and oceans. Snakes are known for their unique ability to swallow prey whole, thanks to their flexible jaws. There are over 3,000 species of snakes, ranging from the harmless garter snake to the venomous king cobra. Most snakes are carnivorous, feeding on small animals like rodents, birds, and insects. They play a crucial role in their ecosystems by controlling pest populations and serving as prey for larger animals.
