They make these sounds at any time and at considerable depths. Besides whistles, dolphins produce clicks and sounds that resemble moans, trills, grunts and squeaks. This acoustic imprinting helps the calf learn to identify its mother. For example, a mother dolphin may whistle to her calf almost continually for several days after giving birth. However, scientists have found no evidence of a dolphin language. Dolphins identify themselves with a signature whistles. Synonymous with the term “sonar” (sound navigation and ranging) and used interchangeably, dolphin echolocation is considered to be the most advanced sonar capability, unrivaled by any sonar system on Earth, man-made or natural.ĭ. With sound traveling better in water than electromagnetic, thermal, chemical, or light signals, it was advantageous for dolphins to evolve echolocation, a capability in which acoustic energy is used, in a sense, to see underwater. It is a process in which an organism probes its environment by emitting sounds and listening to echoes as the sounds bounce off objects in the environment. Millions of years ago, toothed whales developed echolocation, a sensory faculty that enabled them to survive in often murky and dark aquatic environments. Yet the dolphins sonar is much more advanced than human technology and can pin point exact information about its surroundings ranging from size, distance and even the nature of the object.Ĭ. This system is called “Echolocation”, or “Sonar”, just like what a submarine uses to navigate while underwater. In fact, the frequency levels range 10 times beyond what humans can hear.ī. Utilizing their blowholes, air sacks and valves, dolphins can emit a very wide variety of sounds. Even a new baby dolphin, (calf), can detect its mother’s whistle within the pod soon after birth. Each and every dolphin has a different sound just like you and me, a sound that other dolphins recognize as a particular individual. ![]()
