Ranking the Shark Smarts of Horror’s Most Pernicious Predators

Sharks have been terrorizing big screen beaches for decades—way more than they do in real life, actually. But in Hollywood, you have to be more than just a regular old shark to get a fin up on the humans. Sometimes, being a movie shark means you’re a smarter predator. Other times, it leads you to make very bad shark…Read more...

Shark and ray vision comes into focus

Until now, little has been known about the evolution of vision in cartilaginous fishes, particularly sharks and their genetic cousins, the rays. In a new study, it has been shown that all cartilaginous fishes, similar to the marine mammals, have lost the SWS1 and SWS2 opsin genes. Sharks and rays do contain both rod and cone photoreceptors; however rays possess two cone opsin genes whereas sharks have only one cone. Sharks therefore were found to have lost the ability to see colors.

How Are Doves and Sparrows Ending Up Inside Baby Sharks?

Back in 2010, scientists were monitoring a shark population on the Mississippi-Alabama border. They had hauled up a small tiger shark to tag when something strange happened: It puked up feathers. A DNA analysis revealed that the shark had eaten a brown thrasher, a speckled migratory songbird related to the…Read more...

A Rare White Whale Has Been Filmed Off the Coast of Mexico

A whale-watching guide struck white gold last month when he encountered a rare, albino gray whale breaching off the west coast of Baja California, Mexico.Footage of the whale, which tour guide and scuba instructor Manuel Gonzalez posted to Facebook in March, has drawn comparisons to Moby Dick, the white whale of literary legend described by Herman Melville in 1851. Unlike Moby, who was a gargantuan sperm whale with an appetite for New England mariner limbs, the gray whale recorded here was proba...

Shark's-Eye-View Video Captures Epic Seal Chase Through Kelp Forest

Stunning new video footage shows great white sharks hunting seals -- all from the huge predator's perspective. The sharks were fitted with video cameras that recorded some surprising behaviors.The footage revealed that some great white sharks (Carcharodon carcharias) spent part of their days swimming through kelp forests, where cape fur seals (Arctocephalus pusillus) hung out. This finding, scientists say, is unexpected on two fronts.For starters, previous studies showed that great whites us...

Great White Sharks Appear Perfectly Healthy Despite Lead, Arsenic, and Mercury Coursing Through Their Veins

Great white sharks aren’t the unstoppable killing machines of Hollywood’s imagination, but studies have continuously shown that they’re definitely badasses of evolution. A new paper out this week adds to that resume, finding that great whites can easily withstand levels of heavy metals that would kill most other…Read more...

We Need More Games That Let You Play As Animals

Over the last weekend, I finally played some Ape Out. That game has some style. Though as I played it I realized something. Sadly, we don’t seem to get a lot of games anymore that give you control over an animal. That’s a shame, I love these games.Read more...

Newly Decoded Great White Shark Genome Hints at Why They're So Indestructible

The great white shark is impressively terrifying (though not actually much of a threat to humans). But a new study shows that the animal is also an impressive feat of evolution. For the first time, scientists say they’ve fully unspooled the genome of the great white, a discovery that will help us better understand why…Read more...

Can sharks teach us how to cure cancer? Scientists think so

We humans like to flatter ourselves and imagine that we have what it takes to survive here on planet Earth, but our reign pales in comparison to that of sharks. Sharks like the great white have been dominating the seas for millions of years, and they didn't reach the pinnacle by chance.Sharks have incredible biological abilities that give them an edge over many other species, including humans. Now, new research into shark DNA could potentially hold the key to cures for human diseases like ca...

Death metal attracts sharks as it mimics "struggling fish"

TIL: Sharks are attracted to the sound of death metal. Apparently, the "dense tones" of it mimics the "low frequencies of struggling fish." (Damn.) In 2015, a Discovery Channel crew -- hoping to attract a large great white named "Joan of Shark" -- dropped a speaker underwater and played some. Independent: Desperate to feature the 16-foot, 1.6 tonne shark in their documentary, they submerged a speaker to see if the shark would react. Unfortunately they didn't manage to attract Joan, but did c...

Giant 21ft great white shark named Deep Blue spotted off coast of Hawaii

It was the opportunity of a lifetime: the chance for a team of divers to photograph themselves alongside Deep Blue, the notorious great white shark.  But, in the words of one commentator, the resulting headline could easily have read: "stupid human dies chasing a 20ft shark".  The female, one of the largest sharks ever recorded, was photographed feasting on a dead sperm whale nine miles off the coast of Oahu, a Hawaiian island.  It is only the third ever sighting of Deep Blue, who was last spott...

The wilderness has returned to idyllic Cape Cod. That means great white sharks.

On Sept. 14, Wendy Dockray strolled down to Newcomb Hollow Beach, on the shore of Cape Cod, Massachusetts. The waves were mighty that day, so she went to watch the surf pound the shore.  The waves also attracted surfers. "I actually thought, 'Aren't they worried?'" Dockray, whose family has owned a house on the cape for 60 years, said in an interview. The next afternoon, a shark — suspected to be a great white — sunk its teeth into 26-year-old boogie-boarder Arthur Medici. The tra...

Mysterious "shark lair" turns out to be epic buffet

Great Whites travel months to visit what The San Francsico Chronicle describes as a "shark lair" in the Pacific Ocean. Mystified scientists took a deeper look. The sharks’ annual pilgrimage to the mid-Pacific region from the coasts of California and Mexico has baffled scientists for years, not just because it is so far away — it takes a month for the sharks to get there — but because it seemed, on the surface, to be lacking the kind of prey or habitat that the toothy carnivores prefer. But the...

First known omnivorous shark species identified

60% of the bonnethead shark’s diet is made up of seagrass, which they happily graze upon as well as eating fish, crabs, snails and shrimpIt is one of the most radical rebrandings in history: contrary to their bloodthirsty image, some sharks are not irrepressible meat eaters, but are happy to munch on vegetation too.According to US researchers, one of the most common sharks in the world, a relative of the hammerhead which patrols the shores of the Americas, is the first variety of shark to be out...

The Asteroid That Killed the Dinosaurs Also Jumbled Shark Evolution

More than 500 different shark species roam Earth’s oceans: from zippy little cookie-cutter sharks, to the iconic great white, to nightmarish goblin sharks, to 25-foot-long, filter-feeding basking sharks. And it seems that the current equilibrium of shark species we see today arose after the Cretaceous–Paleogene mass…Read more...
