A huge herd of more than 100 whales surrounded a boat off the coast of Australia. This is an incredibly rare event that an expert says has only been recorded once more in the country's waters.
The whales surrounded the boat near Bermagui, about 380 miles from Sydney, in the state of New South Wales, feeding on a large bait ball – a horde of spherical fish.
Simon Millar, owner of Sapphire Coastal Adventures, was training with his staff when they spotted the whales. In the video, whales are seen wagging their tails in the ocean, trying to gather fish at one point.
Millar said it was the second time in history that such a thing had happened in Australian waters.
“It was unbelievable,” he told CNN. “We saw whales swimming all over the area. He was everywhere. We were very lucky.
“The spectacle combined with the sound of whales was truly a unique experience.”
Australia's coastline “comes alive” with whale herds each year between April and November as they swim north of Antarctica, where they spend their summers looking for food in subtropical waters, mating and giving birth, according to the Australian Ministry of Agriculture and Environment.
Their annual migration can cover up to 6,214 miles (10,000 kilometers) and attracts thousands of visitors to coastal cities such as Byron Bay, Harvey Bay and Eden. The majority of whales migrate to the Southern Ocean from September to November.
