Spiders don’t have ears or eardrums like humans or many other animals do. However, they are still capable of perceiving sound vibrations in their environment through other means. Spiders have tiny hairs called trichobothria on their legs and bodies that are sensitive to vibrations. These hairs can detect the slightest movements in the air or on surfaces. While they may not hear sound in the same way we do, spiders can sense and respond to vibrations, which helps them detect prey, communicate with other spiders, and perceive potential threats in their surroundings.
