They might be twice the size of the top ocean predators, but southern right whales don’t take any chances when it comes to protecting their babies.

These marine mammals, which can grow to be upwards of 45 feet long and reach 20 feet even as calves, are known to prefer cloudy waters that will keep them hidden.

And, scientists now say they may even lower their voices to stay off orcas’ radar.

In a new study, researchers have recorded what they say are essentially whale whispers, as the animals hide out in the noisy surf and keep communications to a low to stay unnoticed.

Researchers studied the conversations between southern right whale mothers and their calves in Flinders Bay, of the southern tip of Western Australia.

Previous research has shown that humpback whales whisper to protect their young, too, the team notes.

But, eavesdropping on whales isn’t easy.

‘One of the initial challenges was getting to know the whales in our study area,’ said Mia Nielsen from Aarhus University, Denmark.

‘The number of whales that frequent the bay is low.’

The team tagged resting whales with sound recording devices while they were perched near the surface.

According to the researchers, the mother whales and their calves often stick close together and seek shelter in the surf, where they’re better concealed.

Using the tags, the experts
