A study conducted over the course of decades found that signature noises bottlenose dolphins make are altered by mothers when speaking to calves.
New research using data derived from decades of analysis on how bottlenose dolphins communicate has found that mothers use a sort of"baby talk" that is distinct when communicating with offspring, compared to how they communicate with other adult dolphins.
Zoologist Laela Sayigh of the Woods Hole Oceanographic Institution has studied bottlenose dolphins in Florida in the world’s longest-running study of wild dolphins, and she found that mothers communicate with calves in a more"singsong and musical" way. Sayigh says just as humans change the way we say words, and not the words themselves, when speaking to children, dolphins are sort of doing the same thing.
