The Cull That Is Happening In Australia Is A Revenge Attack
There is no way of knowing which shark attacked the diver recently
This is an endangered species and man in his wisdom try to control nature by killing it.

sharks-ahoy:

According to wildlife conservation much of the sharks’ fin trade uses fins cut from living sharks, called finning. Because shark meat is worth much less, the now finless and often still-living sharks are thrown back into the sea to make room for more of the “valuable” fins. In the ocean, the sharks either die from suffocation or are eaten alive because they are unable to move normally.

This is the kind of thing that everyone needs to be aware of. Shark finning is a horrible practice, and we need to do something soon if were going to have any chance of saving the sharks.

“Sharks don’t cry” is a very sad clip about a young tiger shark. The scenes were all shot secretly by hiding the camera. The film is part of the “Stop Finning” campaign from Sharkproject to call everyone up that butchering of sharks is a threat to our ecosystem.

Exclusive Underwater Shots: Aussie Photog Captures Giant Mako Biting Tail Off Marlin in Mid-Release

When photographer Al McGlashan jumped into the Pacific Ocean off Port Stephens, Australia, earlier this month, his assignment was to film a textbook release of a striped marlin caught and tagged by New South Wales fisheries officials. But a 10-foot mako shark that had been stalking the shoot flipped the script. Streaking past the stunned photographer, the big predator ripped into the marlin as McGlashan captured the ferocious attack from a few feet away. Field & Stream  got a U.S. exclusive on his photos, video and the story behind them.

how crazy

here are some pictures from the 2008 National Geographic’s Great White expedition off  of Mexico’s Guadalupe Island. They made a hydraulic lift to raise theses giants from the sea to get a closer look, take samples and tag them.  oh how I would love to do something like this, I’d be in that water in less then a heartbeat! ^.^

Expedition: Great White

A great white takes the team’s bait—a chunk of tuna on a giant, barbless hook—during a 2008 expedition off Mexico’s Pacific coast.

The hook is attached to a rope strung with buoys used to tire the powerful fish (a trick that failed to work in Jaws) until the shark is ready for the shark elevator.

"Raising these sharks out of the water," expedition leader Michael Domeier said, "gives me an unprecedented opportunity to examine them."

(What a shot! how awesome would that be ^.^)

Able to lift 37 tons, the hydraulic lift had never been used on a marine animal before the great white studies—conducted aboard the research vessel Ocean—began in 2007.

Originally used to lift a power yacht on and off the 126-foot (38-meter) ship, the elevator was retrofitted with substantial railings to haul SUV-size great whites from waters off Mexico’s Guadalupe Island for study.

Data from satellite tracking tags fitted to the sharks during the expedition suggest the adult female great whites found around the island spend much of their lives in the middle of the Pacific Ocean.

After being brought above deck, this shark was secured to the raised platform for about 15 minutes while the crew took blood samples, measured the shark, and attached a tracking antenna to the fish’s dorsal fin.

The giant “shark elevator” has “broken a barrier on our capabilities on great white shark research,” according to the 2008 expedition’s lead scientist Michael Domeier, director of the California-based Marine Conservation Science Institute.

Previously researchers were able to get this close only to dead specimens, because of the danger the sharks pose in the water, he said.

Before the hydraulic lift lowers a Great White Shark back into the ocean, team member Jody Whitworth lifts the shark’s nose, while the ship’s captain, Brett McBride, removes the hydration hose—a device that pumps seawater into sharks’ mouths and over their gills to stave off suffocation.

Shark conservationist Richard Peirce, chair of the U.K.-based Shark Trust, who wasn’t part of the project, said that he “and others in the conservation community would have concerns about catch methods and moving such large animals from the support of the surrounding water. Inappropriate handling can result in damage to internal organs.”

Expedition Great White lead scientist Michael Domeier said he had similar concerns. To address them, “we started with small sharks and gradually worked our way up to larger ones,” he said. “We found it really wasn’t a problem.”

Tests of the sharks’ sex-hormone levels could reveal whether the annual great white gathering to feast on seals around Guadalupe Island doubles as a mating opportunity. Sperm discovered in the claspers, or external sex organs, of local male sharks suggest eating isn’t the area’s only allure.

"Males are not in a state of reproductive readiness year-round, so the presence of sperm is a very strong indication of mating," Domeier said.

The hi-tech tracking tags, developed by researcher Michael Domeier, are designed to transmit up to 120,000 messages and can last for up to six years.

Previously Domeier had relied on conventional satellite tracking devices that “you can just harpoon into the sharks.” But, he said, “they can only track the animals for nine to ten months.”

The new devices are designed to chart migration patterns, which females can take several years to complete.

Because of the bolting required by the new antennas, “we have to capture the shark,” Domeier said.

Each year the endangered predators gather around Guadalupe Island, some 160 miles (260 kilometers) off Baja California, to hunt fur seals and elephant seals during the mammals’ pupping season.

Male great whites return to the site each year, but adult females show up less frequently.

"We wanted to know where they go," Domeier said of the female sharks. "We’ve learned that they go out in the middle of the ocean and then stay there."
