On February 8, Oceana and National Geographic launched an expedition to explore the waters off of the remote Desventuradas Islands more than 500 miles off the coast of Chile. By documenting marine life and habitat the team hopes to persuade the Chilean government to protect more than 60,000 miles surroundinig this archipelago.

After more than a week of expedition, this place continues to surprise us. Yosy discovered a coordinate on the map very close to San Félix that corresponds to a seamount whose peak is only 10 meters deep. This means it is the perfect place to go to with our divers and submarine DeepSee.
We leave early in Argo to look for the seamount. After a few hours, the echo sounder detects 10 meters! Yosy had been right! The group of scientists and cameramen quickly get into the water.
Enric, Avi and I are the fortunate ones that will go in the DeepSee to a completely unknown place. As we start to descend, Avi, our pilot, says, “This is the exact definition of exploration!” And wow, was he right. As my colleagues and I are very excited, before we know it, we have reached 130 meters. Thousands of fish, from brecas to Jack mackerel, sharks to vidriolas surround us.
While we’re going to file this under the “don’t try this at home” category, a promotional video for the GoPro underwater camera showing a free diver from Hawaii swimming with a great white shark is bringing immense amounts of attention to this majestic predator, and encouraging many to rethink the great white’s fearsome “Jaws” reputation.
The video, entitled “A Blonde and a Great White Shark” shows diver Ocean Ramsey (yes, you read that right) approaching a great white shark and stroking the shark’s back before gently holding its dorsal fin while it swims through clear azure waters. With more than half a million views, the video, appropriately released on Valentine’s Day, shows that the great white shark as a magnificent ocean creature to be respected, loved, and protected, rather than a deadly man-eater to be feared. Ramsey’s website, www.waterinspired.com, quotes the Senegalese environmentalist Baba Dioum: “ ‘In the end people will only protect what they love, and only love what they understand . . .’ I hope that by sharing my experiences with sharks I might inspire others to take action and help protect these amazing creatures before it's too late,” Ramsey writes.
With as many as a third of all shark species in the world facing some threat of extinction, the future of sharks has been in peril for some time now. This month, however, French Polynesia and the Cook Islands have taken a stand for sharks, creating adjacent shark sanctuaries covering 2.5 million square miles of ocean – an area nearly equal to the continent of Australia! With this move, French Polynesia and the Cook Islands join Palau, the Maldives, Honduras, the Bahamas, the Marshall Islands, and Tokelau as countries that have created shark sanctuaries, more than doubling the area worldwide now off-limits to shark fishing. This largest sanctuary in the world also bans the possession, sale, or trade of shark products within its boundaries.
On December 6, French Polynesia created the world’s largest shark sanctuary at 1.5 million square miles, and the neighboring nation of the Cook Islands followed suit on December 19 with its designation of its entire exclusive economic zone – an area equal to the size of Mexico at 756,000 square miles -- as dedicated shark sanctuary waters. “We are proud as Cook Islanders to provide our entire exclusive economic zone…as a shark sanctuary,” Teina Bishop, Cook Island minister of marine resources told BBC News.
Today we moved closer to a complete ban on shark finning in the European Union!
The Fisheries Committee of the European Parliament voted in Brussels today to support a strict ban on shark finning, both in European Union waters and on EU ships worldwide. The European Union contains several major shark fishing nations, responsible for 14% of all reported shark catches worldwide.
This new policy would close loopholes in EU’s existing shark finning policy, which allowed some vessels to remove fins at sea. It will have to be approved by the rest of the Parliament before it can go into effect.
Shark finning is a cruel and wasteful practice where fishers cut off a shark’s fins, often while it is still alive, and then toss the rest of the shark overboard to die. Sharks everywhere are facing strong fishing pressures, with many species now classified as threatened or endangered. When only fins are collected, more sharks can be caught, and the species may not be identifiable on-shore, putting threatened and endangered sharks at more risk.
The Shark Conservation Act of 2010 made shark finning illegal in US waters, requiring fishers to bring the entire shark to shore. In the EU, shark finning has technically been prohibited since 2003, but the policy voted on today will remove an exemption that allowed some vessels to continue removing fins on-board and made enforcement of the ban difficult.
Put together, EU countries form the largest shark fishing entity in the world, and we are thrilled that the Parliament is taking this important step to protect sharks in their waters, after several years of campaigning by Oceana's team in Europe. “The vote of the Fisheries Committee sends a strong message to the wider Parliament: the EU, which catches the largest share of sharks worldwide, must set a global example when it comes to policy on shark finning,” says Xavier Pastor, Executive Direction of Oceana Europe.
Editor's note: This is a guest post by Simone Lewis-Koskinen, Program Assistant at SeaWeb, reporting from the Seafood Summit in Hong Kong. Oceana is a sponsor of the summit.
After many months and several thousand emails, phone calls and meetings, the Seafood Summit has arrived! SeaWeb’s 10th Annual Seafood Summit in Hong Kong, kicked off this Wednesday with a series of pre-Summit activities exploring the existing and future horizons of the eco-certification landscape, investment mechanisms for fisheries and local seafood markets. Despite the jet lag, most of the participants were in high spirits and eager to mingle, setting the tone for what’s sure to be the best Summit yet.
The following three days will see a flurry of panels, workshops and meetings that get at the heart of some of the most pressing issues facing the seafood industry. From climate change to Illegal, Unreported and Unregulated fishing, the topics run the gamut, promising a healthy dose of debate and discussion.
Panels addressing tuna and shark issues are particularly likely to spark some heated debates given the cultural and traditional ties to the region. From Friday’s panel discussion on local trends around shark fins and consumer attitudes, to Saturday’s workshop on sustainable shark fisheries, Hong Kong is shaping up to be the perfect place to elevate these dialogues to the next level.
Other sessions likely to provide some interesting food for thought examine the relationship between seafood and the consumer, exploring the various avenues to engage consumers in the discussion. As the Holy Grail for many conservation groups, sessions sharing tools and lessons learned around translating consumer awareness into behavior change are sure to spark a lot of interest.
The Seafood Summit is an annual event hosted by SeaWeb that brings together global representatives from the seafood industry and conservation community for in-depth discussions, presentations and networking around the issue of sustainable seafood. The goal of the Summit is to foster dialogue and partnerships that lead to a seafood marketplace that is environmentally, socially and economically sustainable. The breadth and depth of topics, discussions and perspectives serves as a catalyst for new solutions as one of the premiere events in the seafood community.
Looking back at past Summits, this year’s event represents the first steps into new territory. Traditionally held in Europe and North America, bringing the Seafood Summit to Hong Kong is an important step for helping the sustainable seafood movement engage more effectively with the Asian marketplace. Many of the presentations so far have acknowledged the growing role Asia has and will continue to play in the path towards sustainability. In the days, months and years to come, this initial foray will surely be remembered as setting the stage for many of the lasting relationships formed at the 2012 Seafood Summit.
That man-eating shark from Jaws may be fictional, but that doesn’t stop people from believing that sharks are out to get us — even though it’s not true at all.
Chris Neff, a PhD candidate at the University of Sydney, gave this talk at TEDxSydney about his research on the politics of shark attacks. In it, he identifies the three main misconceptions when it comes to shark-human interactions:
1. Sharks do not “attack”.
2. Rogue sharks don’t exist.
3. People don’t always react negatively to sharks following a shark bite.
Stories of sharks biting humans are uncommon, but get a lot of media attention when they do happen and are often sensationalized. A recent increase in shark accidents in Sydney, Australia prompted calls for a massive culling of the shark population.
But the thing is, sharks aren’t attacking humans maliciously. As Neff says, “trying to govern ungovernable events distracts us from real shark bite prevention.” Instead of killing even more of these important predators, we should be restricting areas where humans can swim and dive and changing our own behavior to prevent future accidents.
Because when it comes to sharks, “we’re in the way, not on the menu.”
Happy Shark Week!
Sharks are the center of a lot of stories and urban legends, but you might be surprised by the truth behind some of the most common myths about sharks. In honor of Shark Week, we’re going to dispel some of the major myths surrounding sharks and shark behavior.
MYTH #1: All sharks are voracious predators, looking to attack anything in sight, including humans.
FACT: While some shark species do have aggressive tendencies, most hunt only to find food (and humans aren’t on the menu). Just like other top predators, sharks make a meal out of animals lower in the food web, keeping the ocean habitat in balance. Only a few species have been known to attack humans unprovoked, and that’s often because of poor visibility or inquisitive bites. There are even species, like the whale shark and the basking shark, that are filter feeders that eat fish eggs, krill, and other microorganisms in the water.
MYTH #2: Sharks do not attack at midday.
FACT: It’s true that there are fewer attacks in the middle of the day, but that’s not because sharks aren’t active then—it’s because everybody’s out of the water eating lunch. Sharks are most active at dawn and dusk, but it’s possible to encounter at shark at nearly any time of day.
MYTH #3: Sharks have walnut-sized brains.
FACT: Sharks are actually pretty smart! They have some of the largest brains in the fish world (along with their close relatives, rays), and their brain-to-body size ratios are similar to birds and mammals. Sharks have been known to exhibit complex social behavior, curiosity, and play in the wild. Many species live in groups and hunt in packs.
MYTH #4: In order to stay alive, a shark must constantly be moving.
FACT: The movement of swimming allows water to pass over a shark’s gills so that they can breathe, but some species have adaptations that allow them to stay still and breathe at the same time. When resting, some sharks can lie on the sea floor and actively pump water over their gills.
MYTH #5: Sharks have no predators.
FACT: Yes it’s true that sharks are at the top of the food chain, but they have a very powerful predator: humans. Each year, tens of millions of sharks are killed for their fins, sport, or caught and killed as bycatch. By removing so many of these important predators without allowing them time to restore their populations, we’re disrupting the balance of the marine food web.
The great white shark, the most iconic shark in the ocean, faces serious threats off the West coast of the United States. Only a few hundred are left, and their populations aren’t recovering quickly — unless we do something. Sign today to help improve protections for great white sharks in the Pacific.
You’ve been waiting for it all summer, and now it’s finally here — Shark Week returns this Sunday, August 12th! Oceana is again a conservation partner, and we’ve got some fin-ominal stuff in store this year.
Need some help preparing for the sharkiest week of the year? Have no fear, we’re here to help! Here are some ways you can gear up for Shark Week’s 25th year:
1. Spread the Shark Week Love
Have your friends over for a watch party. Check out Discovery’s programming schedule and pick out the shows that look the best. ”Great White Highway” follows shark scientists in their effort to solve some of the more mysterious behaviors of the most well-known shark in the world. It’s also narrated by our board member Ted Danson! Check it out on Thursday, August 16th at 9 p.m.
2. Spend Shark Week with Oceana

3. Protect Sharks
For one week a year, over 30 million Americans are glued to their TV sets, transfixed by incredible stories of amazing, powerful sharks. But the true story is that they can’t save themselves from their top predator: us.
Right now there are only a few hundred adult great white sharks remaining of the U.S. West Coast. They are in danger of extinction, but you can help. Sign today to help great whites off the West Coast get listed under the Endangered Species Act..

Make sure that Shark Week isn’t the only time you care about sharks. They’re great to watch on TV, but we need them in the wild, too!
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!
Sharks and rays in the Mediterranean have something to be happy about this week—10 species now have special protections under the Barcelona Convention.
These 10 species—including hammerheads and shortfin makos—have suffered significant population losses. Shark and ray numbers have declined and some species are nowhere to be seen in areas where they were once common.
Today’s decision allows the EU to formalize protection for these important predators. It’s a step in the right direction for the EU, which recently delayed measures that would have limited overfishing in European waters.
“These vulnerable sharks and rays have been granted the legal protection that they urgently require,” according to Ricardo Aguilar, Director of Research at Oceana Europe. Now that the legal protections are in place, the next step will depend on locating where the protected species remain in the Mediterranean, and implementing strict protection measures in those areas.
Sharks and rays are some of the oldest fish in the ocean—the oldest shark relative is estimated to be up to 450 million years old. And now some species have lost 99% of their population in just the last century. Overfishing is a huge threat to these living fossils, and if we want them to be around in the future, we have to act now.
