FEODOSIA, CRIMEA — For decades, we’ve known dolphins were one of the more intelligent species on the planet, but new research may reveal they share a level of communication similar to our own. <br /> <br />At the Karadag Nature Reserve in Russian-held Crimea, scientists used an underwater microphone to record the speech patterns between two Black Sea bottlenose dolphins. Expressing themselves with a series of whistles and clicks, the subjects, Yasha and Yana, were found to adjust the volume and frequency of each sound, forming individual words and sentences. <br /> <br />In addition, the researchers also noticed the dolphins would take turns speaking, waiting for each other to finish their messaging without interruption, which may indicate they were listening. <br /> <br />Yasha and Yana were found to create sentences of up to five words, though they have not deciphered the content of the conversations.
