Bats: Bats are known for their use of echolocation, which involves emitting high-pitched sounds that bounce off objects, allowing them to navigate and locate prey.
Whales and dolphins: These marine mammals use echolocation to communicate with one another, navigate through the water, and locate prey. Dolphins have been known to use echolocation to detect objects as small as a pebble on the ocean floor.
Porpoises: Like whales and dolphins, porpoises use echolocation to find prey and navigate through the water.
Shrews: Some species of shrews use echolocation to navigate through their underground tunnels and locate insects to eat.
Swiftlets: These small birds use echolocation to navigate through dark caves and locate their nests.
Oilbirds: Oilbirds, also known as guacharos, use echolocation to navigate through dark caves and locate fruit to eat.
Blind cavefish: Blind cavefish have no eyes and rely on echolocation to navigate through their underwater environment and locate food.
Rats: Some species of rats use echolocation to navigate through their environment and locate food.
Moths: Certain species of moths use echolocation to locate potential mates.
Elephants: Elephants have been found to use low-frequency sounds to communicate with one another over long distances, which could be considered a form of sonar.
