Blog Tags: Great White Sharks
During Shark Week we love watching majestic great whites on TV, but if we don’t act soon to protect them, recordings will be the only place they exist.
In the Pacific, great whites are important predators. As the largest predatory fish on the planet, they can reach lengths over 20 feet and weigh more than 5,000 pounds. They’re shaped like torpedoes and can swim through the water at speeds of up to 15 miles per hour. Great whites can detect electromagnetic currents in the ocean and have such a sharp sense of smell that they can identify blood in the water from up to 3 miles away. You can’t deny that these are impressive animals.
As fearsome as they might be as predators, they’re not the killing machines that they’re often identified as. They use all those prey-detecting skills to help keep the marine food web intact — without great whites, the ocean’s balance would be thrown off.
But that might be what the future holds, if nothing is done. A recent study found that there may only be a few hundred adults left swimming off the coast of California and Mexico, far fewer than anyone expected. And those that are left face deadly dangers from fishing nets.
Newborn great whites are often killed by commercial fishing gear off of Southern California and Baja California, making it hard for the populations to stabilize.
Sharks have inhabited the oceans for more than 400 million years and now they’re disappearing because of human actions. We’re working to get US great whites the protection they need — sign today to help get great white sharks on the Endangered Species Act.
Shark Week starts on Sunday – stay tuned for lots more sharky updates!
Washington Post environment and politics reporter Juliet Eilperin has a new book out today that explores the science and mythology behind the ocean’s top predators.
In “Demon Fish: Travels Through the Hidden World of Sharks,” Eilperin travels the globe -- she swims with whale sharks in Belize and great white sharks in South Africa -- to investigate how individuals and cultures relate to sharks and how the misperceptions surrounding them threaten their continued existence on the planet.
The book also includes a few nods to Oceana’s shark campaign work, including our work to combat the use of squalane in beauty products, and actress January Jones’ visit to Capitol Hill to advocate for sharks.
But enough about us, be sure to check out NPR’s great interview with Eilperin, and catch her on tour in the coming months. You can see her full tour schedule as well as excerpts, reviews and other information about the book at www.demonfishbook.com.
Here’s a book trailer for “Demon Fish” to whet your appetite:
Holly Beck has an enviable life. A world-class surfer and model, she spends most of the year traveling to the world’s most beautiful places.
Here’s one more reason to envy her -- the Oceana supporter also recently swam with whale sharks and great white sharks. Watch the video below to see footage of Beck swimming within inches of whale sharks and getting giddy when she sees great whites.
After swimming with the great whites she says, “Trust me on this one, the shark didn’t want to eat me.”
Coincidentally, the scientist tagging whale sharks in the first part of the video is Rachel Graham, who has worked with our colleagues in Belize.
Happy spring Friday!
Offshore drilling was on everyone's lips this week. And while we were disappointed with Obama’s decision to open new areas to drilling, he also cancelled four lease sales in the Beaufort and Chukchi seas that had been scheduled by President Bush and committed to conducting significant scientific research and monitoring before any new lease sales are held in those areas -- which is very good news for Arctic people and ecosystems.

…U.S. Department of State banned imports of wild-caught Mexican shrimp if they are collected in ways that threaten endangered sea turtles; in other words, turtle excluder devices are now required in Mexico’s shrimp trawl nets.
…NOAA administrator and marine ecologist Jane Lubchenco talked to Smithsonian Magazine about our changing view of the oceans, dead zones and a cohesive national ocean policy.
…Anderson Cooper dove unprotected with great white sharks in South Africa with “shark man” Mike Rutzen. The video includes disturbing footage of a shark being finned and thrown back into the sea, still alive.
