You know instantly when someone is speaking to an infant
or small child. It turns out that dolphin mothers also use a kind of high-pitched
baby talk. A study published Monday found that female bottlenose
dolphins change their tone when addressing their calves
. Researchers recorded the signature whistles
of 19 mother dolphins in Florida, when accompanied
by their young offspring
and when swimming alone or with other adults.
