Something strange is happening to the oceans. As coral reefs wither and fisheries collapse, octopuses are multiplying like mad. As soon as they perceive weakness, they will amass an army and invade the land, too.
Need a pick-me-up on this dreary Friday afternoon? After checking out some of the nightmare-inducing life forms NOAA’s deep-sea diving robot discovered at the bottom of the Mariana Trench, sleep will be the last thing on your mind.
Researchers working near the Mariana Trench have captured footage of a jellyfish that boggles the imagination.
The Great Barrier Reef is one of the most celebrated ecosystems on Earth—and it’s dying. Months of extreme heat have turned thousands of miles of pristine habitat into an endless watery graveyard. This year’s coral bleaching event comes as a warning. If we don’t bring carbon emissions down fast, the Great Barrier Reef…
Researchers working off the coast of Panama have captured unprecedented footage showing thousands of red crabs swarming together in the oxygen-deprived waters just above the seafloor.
In 1820, a sperm whale attacked and sank the Essex, a whaling ship from Massachusetts. The incident inspired Herman Melville to write Moby Dick, and marine biologists have been wondering ever since if the whales actually engage in ramming behavior. A fascinating new study suggests this may be the case.
It’s often said that we know less about the deep ocean than we do about the surface of Mars. Looking at the 2016 winners of the UK’s Underwater Photography Contest, I can’t help but agree. Life beneath the sea is as alien and entrancing as any ancient, dust-blown crater on the Red Planet.
Every day, troves of hungry marine organisms—shrimp, jellyfish, squid and bony fish—migrate from the ocean’s murky depths to the surface. For the first time, marine biologists have captured the sound of their collective lunch outing. May it be the sonic backdrop to all of your future, jellyfish-induced nightmares.
It’s easy to get excited about new fossil discoveries, but sometimes a second look at an old find can reveal something just as surprising.
A film crew working off the coast of Victoria, British Columbia, has captured remarkable footage of a transient killer whale using its tail to launch a Pacific harbor seal some 80 feet (20 meters) into the air.
Two robotic submersibles, or ROVs, have just plunged into the warm waters off the coast of Hawaii and are plunging 2100 meters to the sea floor to explore. And it’s happening right now, live. You can watch the squid swim by and visit this remote region that’s never been explored by humans.
The more we learn about undersea volcanoes, the more we realize that life can thrive almost anywhere. Now, an Australian research vessel has discovered a new kind of fish living in volcanoes off the coast of the continent. It’s called a scaleless blackfish and it’s adorably ugly.
Illustrated above is a deep-water marine fish belonging to the family Gonostomatidae. More commonly known as bristlemouths, Gonostomatidae are easily the most plentiful vertebrates on on the planet. How many are we talking? Have a guess; I bet you’ll underestimate. (I certainly did.)
To celebrate the 40th anniversary of its original release, Jaws will be shown on the big screen once more on June 21st. Few other movies have cast such a long shadow into the “real” world as the first summer blockbuster. As a marine biologist whose research focuses on shark conservation, I’ve been living in that…
Fisheries biologist John Shepherd once said that “counting fish is like counting trees—except you can’t see them and they move.” This can make animal behavior research extremely difficult. And while increasingly advanced electronic telemetry tags can tell us a lot, there’s just no substitute for seeing a behavior on…
Fishermen working off the coast of Plymouth in Britain snagged a 7-foot-long (2.1 meters) conger eel by mistake after it got tangled in their nets. Weighing in at just over 133 pounds (59 kg), it’s a near-record catch — but this clever optical illusion makes it look much longer than it really is.
Of all the fish in the world, only a few have the capacity to maintain warmth in specific parts of their bodies. But as new research reveals, the deepwater opah has the unprecedented ability to circulate heated blood throughout its entire body, making it the only known fully warm-blooded fish.
Hakai Magazine is a newly launched science publication that will report on science, society, and the environment along the world’s coastlines, which are home not only to nearly half of the planet’s human population, but countless other species of plants and animals.
An international team of marine biologists has recorded an astounding round-trip journey made by a gray whale who ventured from Russia's east coast to the southern tip of Mexico's Baja California peninsula – and then all the way back. At 14,000 miles (22,500 km), it's the longest migration of a mammal ever recorded.
