The snake is a long, legless reptile known for its slithering movement and scaly skin. It belongs to the suborder Serpentes and can be found in various habitats around the world. Snakes come in a wide range of sizes, from tiny threadsnakes to massive pythons and anacondas. They have a unique ability to swallow prey whole due to their flexible jaws and stretchy ligaments. Some snakes are venomous, using their venom to immobilize or kill their prey, while others rely on constriction. Snakes play important roles in ecosystems as both predators and prey, contributing to the balance of nature.
