100,000 dolphins gather mysteriously on the US coast

Recently, a herd of dolphins amounted to about 100,000 children gathered on the coast of San Diego (USA), creating an extremely interesting scene.

'They swim from all directions, you can see them out of sight,' said Captain Joe Dutra.

Dutra is the captain of the Hornblower Cruises. He had the opportunity to see dolphins crowded as he was controlling the cruise ship to visit the sea.

'I have seen many majestic scenes, but this is the most special scene I've ever seen,' Dutra recalls excitedly.

Dolphins often swim in flocks with about 15-200 heads. But the dolphins that Dutra witnessed amounted to hundreds of thousands.

Dutra wished the dolphins had to stretch over 7 knots, and the boat he controlled moved more than an hour before the dolphins concentrated.

Experts have not been able to give any reason why such dolphins gather in such an afternoon.

This is probably a life-long sight once, but in February 2012, it was discovered that dolphins amounted to thousands of children gathered on the waters off San Diego. That is probably a way of highly social animal migration that scientists have not yet discovered.
