What are you waiting for? Today is your last day to donate and get this exclusive 2015 Ocean Wildlife calendar from Ocean Conservancy. Your support will help Ocean Conservancy pursue innovative solutions that will bring lasting, positive change for the ocean.
Traditional fishery management has been a lot like the movie Finding Nemo, where fishery managers focus on the life of a single species of fish. But, as we saw in the movie, single species of fish do not live alone; they depend on habitat like anemones, they encounter predators like Bruce, and there are human impacts such as removing fish from reefs. Our current management system often fails to consider the bigger picture: the habitats that ocean wildlife require at each stage of life, their roles as predator and prey (Bruce’s attitude on fish as ‘friends not food’ doesn’t really hold true in the ocean), the natural variations in populations in different places and at different times, such as sea turtle migrations, and of course the critical and varied impacts of humans—climate change, pollution, ocean acidification, cultural uses, and demands for food and recreation.
In short, we need an ecosystem approach—a modern, big-picture system that maintains the overall health of the ocean ecosystem by explicitly considering the above. Ensuring the long-term viability of fish populations and communities that depend on them requires a greater focus on the fitness and resilience of the ecosystems that support productive fisheries.
The good news is that U.S. fishery managers are recognizing the need to consider the whole ecosystem.A new report by the NOAA Science Advisory Board takes stock of the shift toward ecosystem-based fishery management across the nation. The report found that the use of ecosystem science in fishery management varies greatly by region, and the last several years have proven to be a time of experimentation in the ecosystem approach. We’re getting there, but we’re not there yet.
Marine mammals are some of the most beloved animals in our ocean. Whether you have a soft spot for majestic whales, playful seals or adorable sea otters, you have reason to celebrate. Today marks the 42nd anniversary of the Marine Mammal Protection Act, an important piece of legislation that protects all marine mammal species found in U.S. waters.

I’m pleased to announce that the book launch and exhibition of my Tidal Anatomy portrait series opens at Site 109 in Manhattan on October 21. The images are the result of two years of photographing surfers from an unlikely perspective with my camera placed high above the surfer and beach.
The inspiration for this project came to me while walking along the shore in Montauk, New York, on a raw, windy day in the Spring of 2013. An unusually harsh winter had radically altered the beach, leaving behind arresting scenes of strewn rocks, stratified clay, decaying driftwood, driven sand, and man made debris.

Here at the Taylor Shellfish Hatchery in Washington State, we are facing real threats to our business and our livelihood.
Ocean acidification, largely caused by carbon pollution, can damage shell-building animals, like oysters, clams and mussels. Given the changes we’re seeing in the ocean, it will be increasingly difficult for these organisms to build healthy shells, and will ultimately impact their ability to survive.
We are taking action here in Washington State, but we must do more – for everyone who relies on the ocean.
When I first saw the photo above, I couldn’t believe it was real.
Those are 35,000 walruses – packed together onshore in Alaska.
If you’re saying to yourself “that doesn’t look normal,” you’re right. Packs like this were unheard of before 2007.
The sea ice walruses usually rest on is disappearing, forcing them to come all the way to shore between feedings. These changes to sea ice are putting walruses at great risk.
Now, Shell has proposed a plan to drill for oil in the waters where walruses live, feed, and raise their young. Risky Arctic drilling will cause even more stress for the walruses that are already struggling to cope with the loss of sea ice. We need to stop Shell’s plan.
It’s impossible not to love octopuses. These cephalopods seem to have every evolutionary advantage you could imagine. Here are six of our favorites:
The first and most obvious (it’s even in their name) is that octopuses have eight arms. Their arms are for much more than just reaching a difficult itch. If threatened, an octopus can sever one of its own arms to get away. The lost limb will grow back completely with all of its function. Because of its nine brains and more than half of its neurons being in its arms, individual arms can solve problems—like opening a jar—independently from the rest of the body. Octopuses also taste things by feeling them with their arms and skin.
The beak is the only hard part of an octopus’ body, making it an extremely flexible animal. They can fit through anything as long as their beak can. Octopuses use their beaks to crack into their favorite shellfish meals. They can also produce a neurotoxin that paralyzes their prey and enzymes that help break down their food. The only octopus in the world with venom dangerous to humans is the blue-ringed octopus found in the Pacific and Indian Oceans. Continue reading »
