Last week, the United Nations’ World Heritage Convention went blue. Two of the largest and healthiest marine protected areas on our planet—the Phoenix Islands Protected Area in Kiribati and...
All over the world, people have been witnessing gigantic blooms of tens of thousands of jellyfish where once there were only a few. Fishers find them clogging their nets and costing them dearly. In...
It is a well-known fact that for animals living in the deep sea, food can be scarce. The food that is around usually rains down from above as dead animals and organic particles from plankton living...
For more than two centuries, Boston Harbor has been a dumping ground. In 1773, colonists famously dumped shiploads of tea to protest taxes. But in recent decades, the harbor has received less tea and...
Boring sponges get a bad rap. Their own name betrays them, announcing to the world that they are unexciting, ordinary and quite frankly, boring. However, if ever a misnomer existed, this is it. More...
Imagine: You’re in a small submersible, and you gently settle on the soft muddy bottom at a depth of 12,000 feet. It’s absolutely dark. What will you see when the exterior lights are turned on? Will...
Animals, on land and in the ocean, live in a 3-D world, and they depend on their sense organs and brains to build the mental constructs that allow them to orient and navigate, which is crucial for...
Even on an early winter morning, it was sunny and warm in southern Florida. This was great because, regardless of the weather, Dr. Jon Norenburg and I were going to walk chest-deep into the water to...
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...

Humpback whales ( Megaptera novaengliae ) are the most abundant baleen whale in the nearshore waters around the Antarctic Peninsula. They, along with millions of penguins, seals, seabirds, and other...
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...
Australia’s Great Barrier Reef (or the GBR as it is known to reef aficionados) stretches for more than 2,300 kilometers (over 1,429 miles) and can be seen from outer space. This largest barrier reef...
In recent years, I have taken to watching flying fish along the Maine coast. Not the usual flying fish that skim over tropical seas, but fish dangling from the beaks of flying puffins. Puffins are...
For those of you who have had the opportunity to visit a coral reef , you know that it’s an experience you are unlikely to forget. Coral reefs are among the world’s most magnificent ecosystems. Their...
Sunday, November 21 marks World Fisheries Day , an annual occasion observed in many fishing communities around the world. It’s a great opportunity—even for those of us who do not fish for a living—to...
