Oceanography and marine biology have charted the terrain and species existent at the bottom of the blue bodies of water that make up 75% of the earth’s surface. Now, scientists have discovered to their delight that dolphins have a method of specifically signaling to each other. This consists of a signature whistling sound.
according to BBC News, a Scottish team of erudite scientists found that when the dolphins’ calls were repeated to them, they showed signs of recognition and acted likewise. Dolphins often stick together in groups in the marine depths. They have thus developed a system of vocal utterances that help them keep close to each other. The whistles these super-intelligent mammals use are similar to the human usage of epithets.
The history of research on the topic shows that they use the function often. Furthermore, the younger generation of dolphins learns from its elder peers. But this is the first time that they have shown a visible response to their voices recorded by humans. By employing waterproof speakers the dolphins name calls were aired underwater.
The result was that they showed an active interest upon hearing their own calls. They didn’t respond to other creatures’ calls. This is rather like a human being answering to someone calling his name. So far the only other species to show any signs of human speech mimicry is the parrot.
