The animal known for its ability to echolocate is the bat. Bats are nocturnal mammals that navigate and hunt using echolocation, a biological sonar system. They emit high-frequency sound waves which bounce off objects and return to the bat's ears, allowing them to determine the size, shape, distance, and even the texture of objects in their environment. This remarkable ability enables bats to locate prey in complete darkness, making them highly efficient hunters. Other animals, including dolphins and certain species of birds, also utilize echolocation, but bats are perhaps the most well-known examples of this incredible adaptation in the animal kingdom.
