“Passive bristling” reduces drag, much like the dimples on a golf ball.
Mako sharks can swim as fast as 70 to 80mph, earning them the moniker “cheetahs of the ocean.” Now scientists at the University of Alabama have determined one major factor in how mako sharks are able to move so fast: the unique structure of their skin, especially around the flank and fin regions of their bodies. The team described their work at the American Physical Society’s 2019 March meeting this week in Boston. Read more
Scientific divers from the California Academy of Sciences discover new species of dazzling, neon-colored fish0
Named for Aphrodite, Greek goddess of love and beauty, a new species of fish enchants Academy scientists; only known home is remote Brazilian archipelago.
Now, for the first time, scientists have located and studied these animals in the wild. The orcas are “highly likely” to be a new species, says Robert Pitman, a researcher with the National Oceanic and Atmospheric Administration. Read more
This is the extraordinary tale of how a massive, strange-looking fish wound up on a beach on the other side of the world from where it lives.
The seven-foot fish washed up at UC Santa Barbara’s Coal Oil Point Reserve in Southern California last week. Researchers first thought it was a similar and more common species of sunfish — until someone posted photos on a nature site and experts weighed in.
What transpired after that surprised researchers from California to Australia and New Zealand.
It turned out to be a species never seen before in North America. It’s called the hoodwinker sunfish. Read more
Why the argonaut, or paper nautilus, may be your new favorite cephalopod.
Walking along a shore facing the open ocean, a beachcomber may make an extraordinary find: a paper-thin spiral shell, anywhere from two to around ten inches across, intricately patterned with ridges. These aren’t snail shells. They’re the egg cases of the paper nautilus, the world’s only seafaring octopus. Read more
Can there really be a living creature that’s over five centuries old? It may seem impossible, but scientists have discovered one such beast living in the Northern Atlantic Ocean: a Greenland Shark.
It’s long been known that this particular shark is older than most, but scientists had no idea just how old he was until recently. Now that they’ve pinpointed his age to be 512 years old, he’s claimed the title of world’s oldest living vertebrate. Read more
The eagle is a majestic bird, unfurling its long wings to soar effortlessly through the air.
So it makes sense that the species of ray that also has long wings – stretching at times over 7 feet from tip to tip – to knife seemingly effortlessly along the ocean floor in search of food has come to be known as the eagle ray. Consider it the eagle of the ocean, swooping along in constant search for food. Read more
Most yellow-bellied sea snakes spend their entire lives at sea. They rarely end up on land and are vulnerable there, since their paddle-shaped tails and keeled undersides make crawling difficult. Armed with potent venom, they drift in a vast territory that encompasses much of the world’s oceans, riding the currents and hunting fish near the sea surface. Read more
Underwater peacocks: Baby lionfish smaller than a thumbnail put on a luminous display as they flare out their colourful fins in stunning images captured at night.
- Luminous fish captured at night 100 feet below sea level by diver who was ‘privileged’ to make discovery

- Lion fish flare their translucent fins out to show off a magnificent display of colours including blue and yellow
- When lionfish grow up they are extremely venomous and are often found lurking in quiet areas of a reef
