A male mako shark has been dubbed the “Energizer Bunny” after traveling a distance of half the world, or 13,000 miles (about 21,000 km), in less than couple of years. In accordance with researchers with the Nova Southeastern University’s (NSU) Guy Harvey Research Institute (GHRI), oahu is the longest track recorded during the Atlantic Ocean by the tagged mako shark.
The scientists began monitoring the shark, named Hell’s Bay, in May 2015. Within the novice, he traveled north over the new england of the US before back in the tagging site off of the coast of Ocean City, Maryland. In 2016, the shark made several round-trip journeys through the entire Atlantic, traveling east past Quebec and also as far south as Bermuda. At the moment, the shark definitely seems to be repeating the travel pattern but is staying far better the coast.
The researchers say Hell’s Bay’s jaunts over the past eighteen months have allowed them to identify clear seasonal patterns. The mako shark spends a bitterly cold winter and may far offshore additionally, the entire year on or nearby the continental shelf.
While Hell’s Bay certainly deserves an award with the impressive mileage, Mahmood Shivji, the Director of GHRI, says one of the reasons it turned out capable of the next as they remains to be alive. In December 2016, the non-profit reported that any female shark, tagged about the same time as Hell’s Bay, had become a victim of the commercial long-line vessel. Before her unfortunate death, the shark was able to cover a striking 8,500 miles in the 557 days the group ended up being tracking her. And, she isn’t alone. The latest GHRI study found out that 22% of the tagged makos have been captured or killed by commercial or recreation fishermen.
Mako sharks, among the fastest sharks inside ocean, can swim at speeds of 45 mph during pursuit of prey. Their rapid pace permits them to attack humans all of a sudden, which is why the sharks are very feared and often killed.
Unfortunately, things are all as dire for men and women within the shark family too. Experts estimate that between 70-100 million sharks are killed by humans every year. Given their low reproduction rate, this may not bode well for any species, nearly everyone is whom are already over the endangered list. Hopefully, information gleaned from sharks like Hell’s Bay will enable researchers to educate the population on solutions to protect these majestic animals for future generations.
