A research has taken place by a group of researchers from the University of St Andrews in Scotland on fleeing of whales. Study researchers have said that beaked whales and blue whales are quite sensitive to military sonar used by navies.

The research has found that most common reason of strandings among beaked whales and blue whales is their sensitivity towards sonar. It was not that blue whale, which is the largest animal on Earth, is also not able to bear sonar noise.

Study researchers were of the view that when blue whales come across sonar noise, they stop feeding as well as swim away from that area. Lead researcher Stacy DeRuiter said that the study findings hold utmost importance for those who want to carry out naval exercises.

"Noise pollution threatens vulnerable populations, driving them away from areas important to their survival, and at worst injuring or even causing the deaths of some whales and dolphins", said Prof DeRuiter.

It shall however, be noted that the study findings have been able to uncover the behavioural responses of whales towards sonar responses. The study has not been able to show the actual harm that can be caused by sonar.
