Whales disturbed by man-made sounds underwater

Do you know the man-made sound (sonar) could be harmful to beaked whales according to a new research.Continue to read more about it. Scientists looked at how blue and beaked whales reacted to naval sonar - a technique used by navy vessels that uses sound to communicate and navigate in water. The blue whales, when they were diving for food, moved away as soon as they heard these man-made sounds. This could be dangerous for the creatures, as it could mean they don't get enough food. When the beaked whales heard the man-made sounds they stopped hunting and moved away from the area too. Some scientists don't want the navy to do their training in whale hotspots for this reason.
