 Helicopter pilot Steve Irwin recently caught an amazing aerial view of what he says were tens of thousands of sharks congregating just south of Palm Beach, Florida. Though it is common for sharks to migrate from colder to warmer waters this time of year, what Irwin saw was nothing short of strange, as he said that countless sharks were circling around in waters where there were no visible bait-fish. 'It was truly an amazing sight,' Irwin told reporters at the U.K. Daily Mail . 'I've been a fisherman for 20 years and I also kayak out there and it's common to see [sharks] twist and turn and shoot through the air. They're prevalent at this time of year but what amazed me was the sheer numbers of them.' Owner and operator of Island Marine Services in Fort Pierce, Fla., Irwin estimates that an astounding 100,000 sharks were densely packed in the shallow waters about 100 yards off the coastline for at least 20 straight miles. But the circumstances of the event are confusing, explained Irwin, because there was no specific reason why the sharks decided to stop in the area for so long. 'It's common to see large predatory sharks come in and feed on schools of bait-fish,' he said. 'The odd thing was I didn't see any bait-fish at all!' This shark phenomenon could be somehow related to the many other strange events involving animals, including the unexplained fish and bird deaths that have occurred in recent months ( http://www.selfnews.com/030985_mysterious... ). However, it is difficult to say at this point whether or not there is any correlation, as the increase in shark numbers and lack of bait-fish could just be a simple coincidence.
