How do snakes sense their environment without ears?

Snakes do not have external ears, but they can still sense vibrations in the environment through their bodies. They use specialized receptors in their skin and bones to detect ground vibrations, allowing them to sense nearby movements. Additionally, snakes have a specialized organ called the Jacobsen’s organ (or vomeronasal organ) located in the roof of their mouth. This organ helps them detect chemical signals in the air, allowing them to track prey and detect potential mates or predators. This heightened sense of smell is crucial for their survival, especially in hunting and navigation.
