The Ocean Blog

Not all slugs (snails without shells) are slimy brown pests found in your backyard garden. In the ocean they come in a huge variety of colors — some match the background and are hard to spot, but...
The year 2010 will likely be remembered as a tragic time for the ocean. Yet, despite the oil disaster in the Gulf of Mexico, I have hope for our ocean’s future. Last week President Obama signed an...
Hopefully you've never bitten into a delicious hunk of snow crab meat and instantly spit it out because instead of crab you tasted... aspirin?! If you have, it might have been crab meat infected with...
When snorkeling in the Kahekili Herbivore Fisheries Management Area (KHFMA) in West Maui, I keep an eye out for certain kinds of fish. Not the brightest or the biggest, but those herbivores such as...
I am a member of SCUBAnauts International , an organization for young people passionately interested in the ocean. Of all my experiences as a SCUBAnaut, sharing my love of the ocean with wounded...
We began this journey three months ago, a team of scientists and filmmakers traveling the East African coastline by boat to document and research the status of coral reefs from South Africa to Kenya...
Depending on whom you talk to, jellyfish are either fascinating, a nuisance, a toxic menace, or some combination of the above. Jellyfish plop into the media spotlight when their presence causes beach...
Traveling aboard the Charles W. Morgan , a 173-year-old whaling ship on its 38th Voyage, I’m struck by its paradox: this vessel which spent years chasing and killing whales is now helping us to study...
Bacteria are everywhere in the ocean. They live in the water, on virtually every living and non-living surface, and even inside other organisms . There are 1 million bacterial cells in every...
Sea stars are important members of marine ecosystems, especially in the tropics. We may think of tropical coral reefs as being home mainly to fish and corals, but in fact these habitats are home to a...
Since the dawn of seafaring, humankind has had to deal with the pesky creatures that settle on ships—seaweeds, barnacles, and others that take advantage of the empty real estate provided by a clean...
Diving can be a wild ride that evokes more than a little trepidation, especially in the Pacific Ocean's famously big, cold waves. Waves that are otherwise fun for my weekend surfing can turn a...
Many animals depend on their eyes to navigate, find food, locate mates, and for other important activities. But marine mammals often rely on sound—sometimes far more than sight—for such critical...
When I set out to write a book about mollusks (called Spirals in Time ), I wasn't quite prepared for just how many animals I would get to know. There are somewhere between 100,000 and 200,000 mollusk...
Any floating object in the ocean tends to attract life; fishermen know this and deploy floating buoys to concentrate fish for harvesting. Plastic marine debris is no different and, at microscopic...
Last September, the Citizens of the Sea blog series brought you a story of doom and gloom from the reefs of Bocas del Toro, Panama. That is the time of year we typically study -- and celebrate -- the...
