Sharks grow to “crazy” sizes as these predators feed on excess prey in areas classified as “no-go zones”.
A new documentary has revealed that tiger sharks in the South Pacific have grown a third longer than usual, and great white sharks can reach 20 feet in length. Researchers attribute this boom in size to countries providing more protection to fish populations from the fishing industry.
As spoiled food sources in protected areas have been restored to their original size, tiger and great white sharks have enjoyed an abundance of prey.
Another factor contributes to the creation of reserves that protect terrifying aquatic predators from extermination to extinction. According to the WWF, up to 100 million sharks die every year, mostly due to their fins.
Often referred to as the “dumpster of the sea” because of their endless appetite and willingness to eat anything, tiger sharks are about 12 feet long.
However, Corey Burkhart, a marine biologist and professional shark diver, said she spotted a 16-foot tiger shark in French Polynesia, home to one of the world’s largest shark sanctuaries, established about a decade ago.
She told National Geographic: “I have dived with tiger sharks in many countries and this is by far the biggest fish I have ever seen. Not only long, but also wide. their fins.”
In the National Geographic documentary Great White vs. Tiger Shark, Burkhardt encounters “two of the greatest white sharks ever recorded in Hawaii.”
Typically, female great white sharks are 15 to 16 feet long, while males are much smaller at 11 to 13 feet.
However, in Hawaii, where shark fishing is prohibited, researchers found a 20-foot-long female “huge shark”.
They believe shark cooperation could be another reason for the creatures’ size increase, as sharks now hunt larger prey in coordinated groups.
