Echolocation: Dolphins

Dolphins rely on echolocation to navigate and survive in their aquatic environment. While they have good vision, sound travels faster and more effectively in water, making it a crucial sense for marine mammals. Dolphins produce sounds using air sacs and their melon, creating whistles for social interaction and pulse sounds for echolocation. These sounds help them detect objects and prey, even those hidden under sand. The echoes received in their jaws are processed by their brains, allowing them to interpret their surroundings. Sound is vital for dolphins' navigation, hunting, and communication in the ocean.
