A new study suggests that they are trying to escape noise, reports news.com.au. The study “has found that startled beaked whales swimming away from low frequency sonar boost their energy consumption by more than 30 per cent.” Why is this important? Because the “study showed a big difference in the energy cost of whales swimming normally and attempting to escape danger,” and suggested that “In some cases fleeing whales might run out of steam and become washed up on beaches.”
Noise is not just a nuisance.
