Amphisbaenians are a group of legless reptiles belonging to the order Squamata, which also includes snakes and lizards. They are known for their elongated, cylindrical bodies and burrowing lifestyle. These creatures primarily inhabit sandy or loose soil environments, where they use their specialized heads to tunnel underground. These reptiles are often referred to as "worm lizards" due to their resemblance to earthworms. Amphisbaenians have a unique ability to move in both directions, allowing them to navigate through their subterranean habitats efficiently. They primarily feed on insects and other small invertebrates, playing a role in their ecosystem as predators.
