Today, I'm going to write about THE GREAT WHITE SHARK, I hope it will be interesting... Read on!
The legendary great white shark is far more fearsome in our imaginations than in reality. As scientific research on these elusive predators increases, their image as mindless killing machines is beginning to fade.
Of the 100-plus annual shark attacks worldwide, fully one-third to one-half are attributable to great whites. However, most of these are not fatal, and new research finds that great whites, who are naturally curious, are "sample biting" then releasing their victims rather than preying on humans. It's not a terribly comforting distinction, but it does indicate that humans are not actually on the great white's menu.
Great whites are the largest predatory fish on Earth. They grow to an average of 15 feet (4.6 meters) in length, though specimens exceeding 20 feet (6 meters) and weighing up to 5,000 pounds (2,268 kilograms) have been recorded.
They have slate-gray upper bodies to blend in with the rocky coastal sea floor, but get their name from their universally white underbellies. They are streamlined, torpedo-shaped swimmers with powerful tails that can propel them through the water at speeds of up to 15 miles (24 kilometers) per hour. They can even leave the water completely, breaching like whales when attacking prey from underneath.
Highly adapted predators, their mouths are lined with up to 300 serrated, triangular teeth arranged in several rows, and they have an exceptional sense of smell to detect prey. They even have organs that can sense the tiny electromagnetic fields generated by animals.
Their main prey items include sea lions, seals, small toothed whales, and even sea turtles, and carrion.
Found in cool, coastal waters throughout the world, there is no reliable data on the great white's population. However, scientists agree that their number are decreasing precipitously due to overfishing and accidental catching in gill nets, among other factors, and they are listed as an endangered species.
Heart-stopping moment! great white shark glides under the dangling feet of a New York surfer... who didn't realize what a close call it was until he checked his camera...By James Nye
One stunned surfer came within feet of a fully grown great white shark while surfing off New York City - but only realized when he got home and checked out the footage on his Go-Pro camera.
Riding the waves off Rockaway Beach in Queens in October, the lucky man's camera picked up the distinctive and terrifying shape of the shark gliding beneath him as his legs dangled in the water off his board.
Only seeing how close he came to the most feared predator of the deep when he made it home, the single startling image was posted online at reddit where some questioned its authenticity.
However, noted shark expert Andrew Nosal confirmed to the MailOnline, that the picture does indeed show a great white shark.
'Unfortunately there is no way to tell how far away the the shark is from the boarder and therefore no scale with which to accurately judge the size of the shark,' said Nosal a research scientist at Scripps Institution of Oceanography in San Diego.
'However, the shark does appear mature, making it at least 10-feet in length.'
Hmmm! Interesting, isn't it?
