A new study by the National Institute of Polar Research in Japan found that great white sharks, despite body temperatures that are often warmer than their surroundings, prefer to hunt seals and other prey at slower speeds. These findings, published in this month’s Journal of Experimental Biology, are in contrast to how most endothermic predators hunt. The […]

Great whites may have beat out megalodon in battle for survival

According to new research published in the Journal of Life and Environmental Sciences, megalodon sharks likely went extinct at least one million years earlier than previously thought and direct competition with great whites might be to blame. A team of researchers led by vertebrate paleontologist Robert Boessenecker from the College of Charleston-South Carolina, analyzed fossil occurrence of […]

OCEARCH reveals possible great white gathering spot in Atlantic

Years of study tracking sharks in the Atlantic Ocean may have revealed a warm-weather aggregation point for great white sharks, according to OCEARCH. Researchers have dubbed this region as the Northwest Atlantic Shared Foraging Area (NASFA). Satellite tracking data from the OCEARCH Tracker database system revealed, since 2012, the Atlantic continental shelf waters off North Carolina, South […]

Great White Katharine returns to Florida waters

After going off the grid for nearly nine months, Katharine the great white shark is making up for lost time. The 14-foot female’s satellite tracking device has pinged in three times in the last week roughly 70 miles off the coast of Melbourne. Earlier this year, OCEARCH researchers feared that the battery in Katharine’s satellite tag, […]
