Dolphins speak baby language to their children

When adults talk to young children, they usually change their tone of voice and in other words, use childish language. Now it appears that some mother dolphins also use a unique baby language when interacting with their children.

Quoted from Science NewsSome mother bottlenose dolphins change their distinctive whistle-like sound when they are near their young, a team of researchers reported on June 26 in a study published in the Proceedings of the National Academy of Sciences (PNAS). they give. These parents may be aiming to foster attention, communication, and vocal skills in the baby dolphins, similar to what humans do to raise their children.

During the first few months of life, each dolphin Normal bottle nose (Tursiops truncatus) finds a unique tone or song or special whistle similar to a specific name. Quoted from Leila Saya, a marine biologist at the Woods Hole Oceanographic Institution in Massachusetts, dolphins call each other “names” in the water. Dolphins probably use this method as a “way to keep track of each other,” he says.

But mother dolphins appear to change vocalizations in the presence of their young, who stay with them for three to six years. Saya for the first time in A research published in 2009 by one of his students, realized such an issue; But according to him, that research was just a small part of the much larger current study.

In order to follow up on these observations, Saya and his colleagues analyzed the unique songs of 19 female dolphins without and with their children. During a dolphin catch-and-release health assessment conducted from 1984 to 2018, vocalizations were collected from a population of wild dolphins living near Sarasota Bay in Florida.
