At Karadag Nature Reserve, in Feodosia, Crimea, the researchers recorded two Black Sea Bottlenose dolphins, named Yasha and Yana, conversing with each other in the pool. The pair have lived for 20 years in the swimming pool, which measure just 27 meters by 9.5 meters and is four meters in depth. Without food rewards, a special audio system recorded the exchanges between the male and the female dolphins.

 

The recent tidings about Dolphins is not surprising, as these percoid fishes are known for their eminent intelligence. Marine scientists have found out that they are capable of a “highly developed spoken language,” which resembles human communication.

At Karadag Nature Reserve, in Feodosia, Crimea, the researchers recorded two Black Sea Bottlenose dolphins, named Yasha and Yana, conversing with each other in the pool. The pair have lived for 20 years in the swimming pool, which measure just 27 meters by 9.5 meters and is four meters in depth. Without food rewards, a special audio system recorded the exchanges between the male and the female dolphins.

The studies which have been going on since the 1970s, broke new grounds through digitizing and reanalyzing the recent recordings. The researchers believe that the pulses, clicks and whistles – of up to five words – made by dolphins are listened to attentively by another before a response or reaction is made.

The findings mean dolphins don’t actually “whistle” as has been earlier thought, but rely on vibrations of tissues in their rhinal cavities that are similar to our vocal cords.

“Essentially, this exchange resembles a conversation between two people” wrote lead researcher Dr. Vyacheslav Ryabov in the study, published in the journal Mathematics and Physics.

Ryabov further states,

In this regard, we can assume that each pulse represents a phoneme or a word of the dolphin’s spoken language. The analysis of numerous pulses registered in our experiments showed that the dolphins took turns in producing pulse packs and did not interrupt each other, which gives reason to believe that each of the dolphins listened to the other’s pulses before producing its own.

However, “The dolphin’s speech unfortunately lies beyond the time and frequency characteristics of the human hearing, and is thus unavailable to humans.”

It has long been acknowledged that dolphins possess behaviours not recognized in other animals. Thus, this language exhibits all the design features present in the human spoken language, which unwraps a high level of intelligence and cognizance in these beautiful marine creatures. Their language can be seemingly considered a highly developed spoken language, akin to the human language.

For all the readers who are marvelling about what dolphins communicate and why they need to “talk,” scientists explains — like every other animal, dolphins share information about their identity and stay connected when they dive or while travelling in neritic waters.

“Humans must take the first step to establish relationships with the first intelligent inhabitants of the planet Earth by creating devices capable of overcoming the barriers that stand in the way of using languages and in the way of communications between dolphins and people,” Ryabov concludes.

Humans are, after all, not the only species to possess a high intelligence on the face of earth. We are not the exception, but the rule.
