Often it’s an adaptation of their mother’s signature whistle. They need the guidance of their mother to create the whistling sound independently. The baby dolphins do not produce this whistling sound right after their birth. It acts as identification of the individual dolphin. WhistlingĮach dolphin has its signature whistle, which differs from dolphin to dolphin. A clicking sound and a rattling sound for navigation and understanding about located items. The dolphins use whistling sounds to communicate with each other. Sound navigation, also known as sonar, is the primary method that dolphins use to navigate underwater where the visibility is exceptionally low.ĭolphins transmit sounds and use the sound vibrations that bounce off different objects to navigate.Įven if the area underwater is dark or visibility is very low, the dolphins can still find their swim path and prey easily. Other animals, such as a moth, can jam a bat’s echolocation sonar.Sometimes this jamming occurs by mistake and also can be caused on purpose. Jamming happens when non-target sounds interrupt and cross paths with other target sounds. The echolocation sound system can also be susceptible to jamming. Tenrec Swiftlet Shrew Hedgehog Bat Animals that use echolocation Other than dolphins, several other animals also use echolocation. This communication process helps the dolphins stay connected, which, in turn, helps them avoid predators and find food quickly. The dolphins use this water feature to their advantage while communicating through echolocation. Underwater sound travels five times faster than it travels in the air. The Echolocation method works perfectly underwater because, compared to the air, water is an excellent transmitter of sound. The data an animal receives back is of many kinds. The dolphins receive the returning sound vibrations in their lower jawbone. Through echolocation, the dolphins can even determine the distance of objects and then navigate according to them. The echo sound is then returned to the dolphin when this sound gets bounced off of various objects, helping the dolphin to understand the location of a particular object or prey. While communicating using the echolocation technique, a dolphin will generate high-pitched clicking sounds. How A Dolphin Uses EcholocationĮcholocation is used only underwater, enabling dolphins to locate various objects and prey underwater.Īs sound waves can travel faster in the water than in the air, dolphins can communicate with other species members located miles away. Echolocation is used for navigating, locating prey, and foraging in various environments many animals use. EcholocationĮcholocation is also called biosonar. They can also use echolocation to locate particular objects and organisms underwater. Their exceptional hearing ability helps them navigate underwater, even if it is very murky. Hearing Techniquesĭolphins use sound to communicate with each other and find their prey. The unique structure of the lower jaw bone allows it to conduct the sound into the middle ear of a dolphin. To listen to sounds underwater, the dolphins use their lower jawbones. They close these openings when the dolphins go underwater, making them watertight. Location of a dolphins ear How Do Dolphins Hear?Įven though the dolphins do not have external ears, they can hear sounds through these openings when they are not underwater. However, they can still hear because they have a small ear opening on both sides of their head that leads to the middle and inner ear canal. No, dolphins do not have visible external ears.
