What happened?

In Auckland, the largest city in New Zealand, on the coast of Golden Bay on the night of 10 February were found 416 black dolphins – grindu. The exact number reported by the Department of conservation of New Zealand. The New Zealand Herald reports that during high tide was able to save only one-fourth of the total. However, the rescued dolphins are in no hurry to swim away from the shore – they remain in the Bay. Experts fear that with the low tide they can come back.

What are the reasons?

The causes of the accident are still unknown – the blood samples only were taken. But since this case is not the first in the entire history of observations, then there are several versions. Mass emissions resemble acts of suicide. Thus dolphins can make an escape from predators in the hope that the land will necessarily be people who can help them.

It is not excluded that at the hearing of dolphins affected by military sonar. According to a study by the Hawaii Institute of marine biology (2009), Dolphin under the action of sonar may lose hearing for 40 minutes, why loses orientation in space. According to Dr. Aran Mooney, a new theory will help to explain some of the earlier cases. For example, in March 2000 on the coast of the Bahamas beached whale 16 after testing American sonars for 16 hours. There is another hypothesis that the strange behavior of dolphins is nothing like the instinctive support of a comrade. In some form the shores sounds of the surf can be exactly similar to the call for help.

Where?

Marine animals are often dumped on land in Tasmania and Australia. New Zealand is also located in this region. The explanation for this regional specificity is not yet found. Such emissions occur ashore in Japan, South and North America.

Previous incidents

5 years ago on the beach of Cape cod in Massachusetts, was found on 30 of the dolphins, only 11 of whom survived and returned to the familiar surroundings. But when rescue professionals encounter difficulties. Katie Moore, Manager for marine mammal IFAWreported that the dolphins, whom have managed to return to the ocean, have made repeated attempts to return to shore to their dead relatives.

And in September of 2016 received wide publicity in mass ejection horseshoe crabs in Japan. For the previous year killed about 490 species of these ancient arthropods. The latest incident was 20 years ago. Research fellow, Kyushu University, Hiroko Kioka believes that the problem lies in the shortage of oxygen in the water.

“the Rise in sea level caused by global warming, the shortage of places for laying their eggs and lack of power could lead to the death of horseshoe crabs”.

What do the experts say?

TV presenter and scientist-zoologist Nikolai Drozdov in comments RT:

Nikolay Drozdov“It is always associated with pollution. People harm the environment, in particular marine, so this response of the animals is obvious. You just need to be more careful about nature, and then we can avoid such terrible consequences.”

In continuation of the topic

As reported TASS on Sunday, February 12, some of the dolphins-whales were able to swim away from the Cape, Farwell during a night tide. However, they continue to be in shallow water. Herb Christophers, a representative of the environmental Agency of New Zealand reported that on the shore were 17 live mammals, which is all kinds of help to return to his native habitat.
