To avoid predators, mother and baby humpbacks communicate in ‘whispers’. But Prof Lars Bejder suggests more large vessels and increased noise in Ningaloo’s nursery will ‘mask’ humpback whale communication. That means mothers won’t hear their calves, and vice versa. This isn’t just stressful – it reduces their chances of survival. See Shannon Beattie’s story in The West Australian.
