Humans may not be only ones to use grammar and vocabulary to speak and communicate. Scientists believe dolphins also use words and sentences to speak to each other. We have known for long time that dolphins can communicate. New research suggests that this communication is similar to conversations humans have. Scientists say clicks, whistles and other sounds that dolphins make appear to be sentences that let sea creatures send messages to each other. dolphins use their language to identify themselves, have relations with other dolphins, and do things together. Scientists say that one day, we may be able to understand dolphin language and talk to dolphins.

Researchers at Karadag Nature Reserve in Crimea made discovery that dolphins had their own language after recording two Black Sea bottlenose dolphins. dolphins were named Yasha and Yana. The scientists noticed that one dolphin listened to what other was saying and then replied. Lead researcher Dr Vyacheslav Ryabov said: "This exchange resembles conversation between two people." He added: "This language exhibits all design features present in human spoken language. This indicates high level of intelligence and consciousness in dolphins." Dr Ryabov said dolphins' language is, " highly developed spoken language, like human language."
