The shape of snakes is long and cylindrical, allowing them to move efficiently through various environments. Their bodies are typically flexible, which helps them navigate through grass, trees, and water. Snakes lack limbs, relying on their muscles and scales to propel themselves forward. Most snakes have a tapered tail that aids in balance and movement. The head is distinct from the body, often featuring specialized structures like fangs for venom delivery in venomous snakes. This streamlined shape is essential for their hunting and survival, enabling them to blend into their surroundings and escape predators.
