Fish are friends, not food: Meet the world’s first known omnivorous shark

sudshr47 September 5, 2018

It’s not exactly as vegetarian as Finding Nemo‘s Bruce, but this grass-eating shark could come close to taking the “fish are friends, not food” pledge.

Researchers claim they’ve identified the world’s first known omnivorous shark, which eats both underwater animals and plants.

In a new study published by researchers at the University of California-Irvine and Florida International University, the bonnethead shark, which dwells in seagrass meadows off the Atlantic and Gulf of Mexico coasts, was found to be not solely carnivorous, as previously thought — it’s been sighted having a good nom on that seagrass on multiple occasions.

Caribbean Sea Conservation Ocean Science Sharks

A dominant shark lurks in the deep, dark ocean. Meet the sixgill.

sudshr47 August 25, 2018

On a balmy Caribbean evening in August, crew members aboard the the 184-foot exploration vessel the Alucia tied dead fish to the front of a small yellow submarine.

They tightly wound the fish to a metal pole extending out from the undersea craft to tempt whatever might be lurking, three thousand feet below.

But Dean Grubbs, one of the researchers preparing the bait, didn’t intend to catch anything. Grubbs, a shark scientist at Florida State University, only hoped to attract a little-seen creature that largely dwells in the lightless ocean depths: the sixgill shark.

Biofluorescence Glowing Fish Ocean Science Sharks

These creepy sharks glow bright green in the dark. Here’s why.

sudshr47 June 14, 2018

The largest disco on Earth is happening deep beneath the surface of the ocean, and no, you’re not invited.

New footage from National Geographic researcher David Gruber and his team reveals a shark glowing bright green 120 feet deep in Scripps Canyon off the coast of Southern California. To those of us who are used to our sharks having skin that doesn’t glow, this might come as a shock. But Gruber’s observation, though relatively new for us, is how it’s always been for these sea creatures — we just couldn’t see it until now.

The fish in question, known as a swell shark, glows thanks to a process known as biofluorescence. This essentially means that the shark is absorbing blue light and re-emitting green light. Scientists suspect that this kind of behavior has something to do with how these sea creatures attract mates. Read more…

Conservation Marine Scene Reefs Science Sharks

Remote archipelagos teeming with sharks aren’t as pristine as they seem

sudshr47 March 7, 2018

When swimming in the waters of the isolated Chagos archipelago in the Indian Ocean, a half-dozen sharks would sometimes surround Francesco Ferretti.

“You are in another world,” said Ferretti, a marine ecologist at Hopkins Marine Station of Stanford University. “You feel like you’re in one of the last remaining paradises of the planet.”

The medium-sized reef sharks here are harmless (to humans). The coral is vibrantly colored. The water pure.

And to a large degree, it’s an illusion.

“When you see these places you think there’s less human impact,” said Ferretti in an interview. “However, things are not so simple.” Read more…

Discovery Channel Donald Trump Entertainment Sharks Television

We asked the network behind Shark Week about Trump’s shark fears. Here’s what it said.

sudshr47 January 19, 2018

There’s a lot to fear with Donald Trump in the White House — but his worst fear? Sharks, apparently. Which isn’t sitting well with Discovery Channel.

Mashable reached out to the Shark Week network after reading a report alleging that Trump once said, “I hope all sharks die.” Its response was measured.

“Shark Week celebrates the wonder of these majestic creatures and their critical importance to the ecosystem,” a Discovery Channel representative told Mashable when asked for comment about the president’s Shark Week viewing habits and fears. “Their safety and conservation is the most important message conveyed throughout the week.” Read more…

Yes, everything is hard, but at least your family isn’t being circled by a great white shark

sudshr47 December 28, 2017

Sharks are invariably a part of the sea in Australia, but this encounter was a bit too close for one family.

Jodie Brown was on a boat with her family of seven on Tuesday near the town of Port Victoria in South Australia, when a great white shark estimated to be five metres long began to circle them.

“It just swam up to the boat from behind and it was just circling us for about 20 minutes, it would just go round and come back again,” Brown told The Advertiser.

“We had to leave in the end to take two girls back to shore because they were freaked out, but the whole time it was just amazing.” Read more…

We wish this insanely creepy pre-historic shark was never found alive

sudshr47 November 14, 2017

It’s one thing to have a nightmare about a demogorgon—that’s at least not real. This creature on the other hand, is very much of this Earth—and there’s at least one out there that is very much alive.

While working on a project, European Union researchers unexpectedly came across (and managed to catch) the elusive frilled shark. According to recent reports from BBC, the shark, whose species has existed unchanged since around 80 million years ago, was found off the coast of Portugal.

NUMAZU, JAPAN - JANUARY 21: In this handout picture released by Awashima Marine Park, a 1.6 meter long Frill shark swims in a tank after being found by a fisherman at a bay in Numazu, on January 21, 2007 in Numazu, Japan. The frill shark, also known as a Frilled shark usually lives in waters of a depth of 600 meters and so it is very rare that this shark is found alive at sea-level. It's body shape and the number of gill are similar to fossils of sharks which lived 350,000,000 years ago. (Photo by Awashima Marine Park/Getty Images)

The captured frilled shark caught in Portugal is about five-feet long and was caught around 2,300 feet underwater, off the Algarve coast. Some have also been discovered in Australia, New Zealand, and Japan (like the one shown above). Read more…
