They will?
I’ve never heard that before!
My grandson was one and a half when we went whLe watching. When he’d cry the orcas came right up to the boat to help him. The boat owner said that’s the most action he’d ever seen. I asked him why didn’t he just play a tape of baby crying and he said the whales know the difference, but when a real baby cries they can hear it from pretty far away, and they come to save the baby in distress. Skyler was the whale whisperer that day.
Of course orcas are actually dolphins.
