2023年5月19日 · Yes and no, Sara Ruane, a herpetologist at the Field Museum in Chicago, told Live Science. Like many reptiles, snakes don't have an external ear structure. However, they do have ear...

2023年3月2日 · Over the past two decades, a large swath of research has grown to suggest that — because snakes don’t have external ears and eardrums — they register noises through sound-induced vibrations that travel through the ground, perceived through their bodies.

2023年12月14日 · However, a simple look at any snake will confirm it doesn’t have an outer ear. Instead, they have a single middle ear bone and an inner ear. The internal ear is responsible for processing sounds.

Snakes actually have formed an inner ear, with no eardrum, that is directly connected to their jaw bone (quadrate bone). This bone rests on the ground and slightly moves in response to vibrations while they slither on the ground.

2024年10月24日 · While many reptiles have external ears that help them hear sound waves, snakes only have an internal ear, which picks up vibrations from the ground. This ability allows them to "hear" in a completely different way from other reptiles, relying on their jawbones to detect movement and vibrations.

2015年12月4日 · Snakes don't have ears or eardrums like humans have. In fact, this lack of external ears — and observations that snakes don't tend to respond to sounds — led many scientists to conclude that snakes were deaf .

2021年10月6日 · Directly behind their eyes, snakes have two ears just like other reptiles. They do not have external ears (commonly referred to as ear flaps, pinnae, or auricles), but they do have small holes on the sides of their head that are ear openings.

2021年5月3日 · Snakes lack both an outer ear and middle ear, according to a 2012 study in the Journal of Experimental Biology. However, they have one middle ear bone that connects the inner ear to the jaw. This enables snakes to hear vibrations, such as a …

2023年6月7日 · Snakes do not have ears: While it is true that snakes lack external ear structures, they have internal ear anatomy that enables them to detect sound waves. Snakes cannot hear airborne sounds: Studies have shown that snakes can detect and respond to airborne sounds, albeit at low frequencies.

Snakes have what we call vestigial ears. Their internal hearing structure contains all the elements that most other animals possess. The real problem is the absence of the external ear. Because snakes don’t have external ears, they are unable to detect sounds the same way we do.
