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.

Last weekend, two divers exploring the waters off the coast of Cornwall, England, had a surreal encounter with a roughly 5-foot-long barrel jellyfish. Continue reading Divers Encounter a Human-Size Jellyfish Off the Coast of England
The word “scallop” usually evokes a juicy, round adductor muscle—a seafood delicacy. So it isn’t widely known that scallops have up to 200 tiny eyes along the edge of the mantle lining their shells. The complexities of these mollusk eyes are still being unveiled. A new study published in Current Biology reveals that scallop eyes have pupils that dilate and contract in response to light, making them far more dynamic than previously believed. Continue reading What Scallops’ Many Eyes Can Teach Us About the Evolution of Vision
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. Continue reading The World’s Most Ancient, Elusive Sharks Were Finally Caught on Video
A family of tourists in Canada’s Steveston Harbor recently got a treat when a friendly-looking sea lion sidled up to them in the water. The adorable animal came up to the edge of the wharf, and the family started feeding it. One young girl sat down to get a better look. That’s when the treat became a shock: the sea lion lunged upward and, in one fluid motion, grabbed a mouthful of the girl’s dress and yanked her down into the water.
One November night each year, beneath the full moon, more than 130 species of corals simultaneously spawn in Australia’s Great Barrier Reef. Some corals spew plumes of sperm, smoldering like underwater volcanoes. Others produce eggs. But most release both eggs and sperm, packed together in round, buoyant bundles as small as peppercorns and blushed in shades of pink, orange, and yellow.
It’s not an unusual sight out in the ocean: blue whales slurping up clouds of krill. But researchers most often have a boat’s eye view for this event. Now new drone footage from Oregon State University is giving them a whole new perspective on how these massive creatures, the largest animals on the planet, catch their dinner.
