Russian researches at the Karadag Nature Reserve claim to have recorded dolphins having a conversation 'just like two people." The recording was done using an underwater microphone, capable of distinguishing between different animal "voices."
Mammals have long been known to have advanced forms of communication including the use of distinctive whistles and clicks. However, the new recording shows that dolphins are capable of altering the frequency and volume of their pulsed clicks to create "words." According to the Telegraph, the researchers found that the dolphins could create sentences of up to five "words."
The recording took place at the Karadag Nature Reserve in Feodosia. Two Black Sea bottlenose dolphins were found communicating with each other in a pool. The dolphins are called Yana and Yasha. The scientists also found that each dolphin listened to the complete sentence before replying.
The scientists revealed that each pulse produced by dolphins was distinct from each other. It was also possible to tell them apart by "the set of spectral components in the frequency domain." They explained that the dolphin language possesses "all the design features present in the human spoken language."
SlashGear reported that the scientists have called for the development of devices for making communication between humans and other intelligent mammals possible. In 2007, Australian scientists were able to distinguish dolphin whistles to indicate "Hurry up" and "I'm here, where is everyone" among other sentiments. Scientists in Florida found that dolphins increase their communication when they undertake a difficult task.
