Two Mako Sharks Tagged by NSU Researchers Spending Spring Break Off South Carolina Coast
Sharks Tagged as Part of NSU’s Guy Harvey Research Institute Ongoing Studies
Who knew that sharks like to hit the beach for Spring Break, too!
Well, they aren’t exactly hitting the beach, but two mako sharks tagged by Nova Southeastern University’s (NSU) Guy Harvey Research Institute (GHRI) are enjoying the waters off the South Carolina coast.
“We’ve been tracking mako sharks for many years, and we’re continually amazed at their migratory patterns,” said Mahmood Shivji, a professor at NSU’s Halmos College of Natural Sciences and Oceanography. “Many of our makos have made huge journeys very far offshore into the Atlantic, but these two males decided just to migrate up and down the U.S. coast over the past 10 months, although still covering more than 4,000 miles each. Just when you think you know what they will do, the sharks surprise you – there is still so much to learn about these truly incredible animals.”
Shivji is the director of NSU’s GHRI, which has been tagging and tracking various shark and billfish species since 2006. This program is in partnership with world-renowned artist, scientist and explorer Dr. Guy Harvey. The mission of the GHRI is to provide the scientific information necessary to understand, conserve and effectively manage the world’s marine fishes and their ecosystems.
The two mako sharks in question, both males, are Bruce and Matt J. – so named by those who sponsored the satellite (SPOT) tag that pinpoints their location as they swim in the ocean. What’s interesting is that both of these animals have now been detected very close to each other off the Carolinas, 10 months after being tagged very close to each other off Ocean City, Maryland and going as far north as Massachusetts in the meantime.
“These animals swim incredibly long distances both on the continental shelf and out in the open ocean, but they do tend to return to nearly the same spots each year,” said Shivji, who is also director of NSU’s Save our Seas Shark Research Center. “Humans have GPS systems and we still get lost, so it’s pretty remarkable that these animals can return to the same locations year after year – without the help of a smartphone!”
Shivji said his researchers have special interest in understanding mako shark migratory behavior because this information is essential for proper fisheries management and conservation of this internationally roving and heavily fished species.
