Legless lizards are often mistaken for snakes, prompting questions about their behavior, particularly whether they bite. This confusion stems from their similar appearance, yet these creatures possess distinct characteristics. Understanding these differences clarifies their nature and mitigates unwarranted concerns.
Do Legless Lizards Bite?
Yes, legless lizards can bite, though such occurrences are uncommon. Like many animals, they possess teeth and use them defensively if threatened or handled improperly. Biting is typically a last resort for these animals. Their primary defense mechanisms often involve attempting to escape or, in some species, detaching a portion of their tail to distract a perceived predator.
Distinguishing Legless Lizards from Snakes
Distinguishing a legless lizard from a snake involves observing several anatomical features. One difference lies in their eyes: legless lizards possess movable eyelids and can blink, a capability absent in snakes, which have fixed, transparent scales. Another identifying characteristic is the presence of external ear openings, which legless lizards have as small holes on the sides of their heads; snakes lack these visible ear structures.
The scales on their undersides also differ. Legless lizards generally have uniform scales across their body, including their belly. Snakes, however, feature broad, specialized belly scales known as scutes, which aid in locomotion. The tail length proportion also varies; legless lizards often have tails comprising half or more of their total body length, and many species can detach their tails as a defense mechanism. In contrast, snakes typically have proportionally shorter tails and cannot shed them.
The Nature of Their Bite
A bite from a legless lizard is generally not dangerous to humans. These reptiles are not venomous. Their bites are typically mild and superficial, often feeling like a pinch or a scratch. It is uncommon for their bite to break human skin, and serious harm is unlikely.
If a bite occurs and the skin is broken, basic first aid is usually sufficient. Cleaning the wound thoroughly with soap and water is recommended to prevent potential infection, as with any minor scrape or cut. There is no need for antivenom or specialized medical treatment.
Understanding Their Biting Behavior
Legless lizards exhibit biting behavior primarily when they perceive a threat. This defensive action is typically triggered by being cornered, startled, or handled roughly. Biting serves as a final warning or escape attempt rather than an aggressive act. They prefer to avoid confrontation and usually try to flee if disturbed.
To avoid being bitten, observe legless lizards from a distance and refrain from handling them. Allowing them space and not provoking them significantly reduces the likelihood of a defensive bite. Respecting their natural habitat and behaviors helps ensure both human and animal safety.
