Do dolphins speak to their young in ‘baby talk’, like humans? FMTNews FMTLifestyle
Parents often use a high-pitched or sing-song voice to talk to their babies. As it turns out, humans aren’t the only ones in the animal kingdom to adapt the pitch of their voice to communicate with their offspring: according to new research, dolphins do the same.
Biologists have known for decades that these mammals have a complex, structured communication system. They produce social sounds to “talk” to one another, as well as echolocation clicks to hunt and orient themselves in their environment. To verify this hypothesis, researchers analysed the whistling sounds of around 20 bottlenose dolphins in the waters around Sarasota Bay, Florida. These were recorded over a period of 34 years, when the females were with or without their young.
This study provides further proof of the richness and versatility of animal language. Indeed, many animals speak differently to their babies than to their peers – rhesus macaques and squirrel monkeys make unusual sounds, including grunts and nasal moans known as “girneys”, to attract the attention of the young of their species.
