EVERY YEAR, GREAT white sharks travel over 12,000 miles from South Africa to Australia, charting a nearly perfect straight line across the ocean. And every year, they turn around and travel back. There are no street signs to guide them and, for much of the journey, no stable landmarks by which they can set their course. Currents and water temperatures change. The sun sets at night, the stars disappear during the day. But the sharks carry on.
In 1979, researchers in the Eastern Pacific Ocean scooped up a small, never-before-seen shark with distinctive pockets near its gills. Another “pocket shark,” as the animal was dubbed, was not seen again until 2010, when a National Oceanic and Atmospheric Administration ship found one in the Gulf of Mexico. But as Mindy Weisberger reports for Live Science, a new study has revealed that the two specimens do not belong to the same species—highlighting just how much scientists have yet to discover about the creatures that live in the mysterious deep.

The Greenland shark is one of the world’s largest marine species, reaching lengths over 19 feet. And yet these fish, which prefer the deep, cold waters of the Arctic and North Atlantic oceans, have largely eluded scientific study.

A South African shark-watching hotspot has recently turned into the scene of a seaside horror movie. For several months, enormous great white shark corpses have been washing up on the Gansbaai beaches, often missing their livers as if feasted upon by cetacean Hannibal Lecters. But this is no movie—it’s just biology, ruthless as ever.
Three different people were bitten by a shark during three different attacks in under three hours at a Florida beach, local authorities have confirmed. The shark encounters occurred in the same general area at New Smyrna Beach Sunday, WFTV reported. All three victims suffered lacerations, though none of the injuries are believed to be life-threatening.
Great white shark pups are spending their youth in the waters off of Long Island’s South Shore, marine biologists believe. The research group OCEARCH has identified what appears to be the first great white nursery in the North Atlantic after catching and tagging nine young sharks during a two-week expedition.
If you’re counting on technology to radically extend your lifespan, you’ll want to pay close attention to what’s happening with the Greenland shark. According to a new scientific paper, this mysterious deep-sea dweller can live up to 400 years, making it the longest-lived vertebrate on Earth.
