A new study published in the journal Biology Letters, has revealed that North Atlantic right whales alter their calls to their young in order to protect them from predators.
Normally right whales use an "up call", rising ‘whoop’ sound to communicate with each other. According to the latest research, right whale mothers will ‘whisper’ to their babies in a much shorter and lower tone that can only be heard in the immediate vicinity.
This type of communication seemed to take place only between mothers and their young, and not among juvenile or pregnant whales. It is thought that by communicating over shorter distances like this might be a way of not attracting the attention of predators like orcas who might be present in the area.
A similar behavior has been noted in other species of whale, including the southern right whale and humpback whale.
Only around 400 North Atlantic right whales survive along the East Coast of the United States and Atlantic Canada.
