Search for the whale 'Forever Alone' most on Earth

Scientists are looking for a lonely whale with an unusual cry, wandering across the Pacific .

Last week, a group of scientists set up a project to try to find the world's "lonely" whale by following its route in the North Pacific.

Since the late 1980s, while patrolling and listening to a North Pacific submarine, US naval officers have heard, recording the unusually high sounds of a marine mammal. But for more than 20 years, they have not really seen it with their own eyes.

Experts believe that this giant mammal could be a fin whale, or a blue whale or a hybrid between two species.

In 1989, Dr. William Watkins of the Woods Hole Oceanographic Institution in Massachusetts (USA) began studying the recordings and found that the whale song was unusually high.

Most blue whales "sing" and communicate with each other at frequencies of about 15 - 20Hz, but this "lonely" whale emits signal waves at 52Hz. Therefore, other whales cannot hear the whale's emitting signal. That is why the whale in the North Pacific is called the "lonely" whale in the world.

The voice of the most "lonely" whale in the world has dwindled a bit because of "old age" , but still recognizes.

Dr. Watkins and his colleagues set up a net and watched the whale's adventure however, this is extremely difficult. However, the successive generations Dr. Watkins never gave up. They said, this cry often echoed throughout the ocean in autumn and winter. It was a little depressed because of "old age" , but it was still recognizable.

Currently, scientists are still trying to find this particular whale. Of course, because people are so small and the world is immense. And maybe, this whale is not the only FA creature on Earth.
