How do snakes hear without ears? Read fascinating facts about snakes

Around the world, many people fall victim to snake bites. It's important to note that snakes only strike in self-defense or if they feel threatened. Despite their lack of visible ears, snakes can detect even the slightest sounds. This ability is so remarkable that people with acute hearing are sometimes referred to as having "snake ears." But how do snakes hear without ears? Let’s explore the fascinating way snakes perceive sound.

Do snakes hear? While snakes lack external ears, they do possess inner ears, allowing them to detect sound vibrations. Unlike humans, who can hear a range of 20 to 20,000 hertz, snakes are sensitive only to sounds between 200 and 300 hertz. They primarily sense vibrations through the ground. Snakes use their jawbones to transmit these vibrations to their inner ears, helping them detect and recognize sounds. Interestingly, while snakes are not very adept at hearing, they communicate using their tongues.

Snake skin has unique properties that allow them to sense vibrations and sounds through their skin, which then travel to their brain. This ability helps snakes detect potential threats. Interestingly, not all snakes lay eggs. While many believe that all reptiles, including snakes, lay eggs, only about 70% of snake species do so. The remaining 30% give birth to live young, particularly those in colder climates where eggs would not survive.

Snakes do not have eyelids, which contributes to their intimidating appearance. Unlike other animals, snakes' eyes remain open constantly, even when they sleep, because they lack eyelids. To protect their eyes, snakes have a thin, transparent membrane called the "spectacle" or "brille" in German, meaning "glasses." This protective layer covers their eyes, keeping them safe and clean.

Snakes use their tongues to "smell" their surroundings. Although they have nostrils, these are not used for smelling. Instead, snakes rely on their tongues to pick up scent particles from the environment. This remarkable ability is often described as "smelling in stereo," allowing them to detect scents with incredible precision.
