The Ocean Blog

The ocean is home to a phenomenal diversity of marine organisms. They have evolved to inhabit warm waters near the equator and the icy waters of the Earth’s poles. Marine life takes advantage of the...
Stare at a tide pool and you will often see a crust of pink coating the bottom. No, this is not bubblegum from some careless teenager’s shoe: it’s a stony kind of seaweed that, like other seaweeds,...
Since late April, the world has watched a devastating oil spill from a BP drilling rig spread throughout the Gulf of Mexico and become one of the worst environmental disasters in the history of the...
Large whales are notoriously hard to study. Except when rising to breathe, they swim beneath the ocean's surface out of human sight, which makes it difficult to find and track them. They often live...
Welcome to Citizens of the Sea , a new blog series where ocean life comes to life. Our book by the same name came out in September, but no sooner had it gone off to the printer than new ocean stories...
When we think "Africa," we think of the "Big Five"—lions, elephants, leopards, buffalo and rhinos—that crisscross the African Savannah. Few would imagine that there could be more natural beauty on...
Reef sharks rarely get any love. These sharks, comprising several species, loiter around coral reefs, snacking on small fish, squids and crustaceans. And while their size is nothing to smirk at—5-10...
Until recently we were farmers on land and hunter-gatherers at sea, but how we get our seafood is changing rapidly. With demands for seafood growing and catch from wild fisheries stagnating ,...

In honor of Mother's Day, the Citizens of the Sea blog salutes ocean-going mothers everywhere. Especially a 60 year-old albatross named Wisdom. She holds the seabird records for both oldest bird and...
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...
Polychaete worms are not your average cringe-inducing, writhing worms. (Okay, maybe some are.) They are fascinating, varied, and a critical part of our ocean. The visual variety among the more than...
Reef biologists over a certain age are haunted by memories of what glorious places Caribbean reefs once were. In our youth we studied them for all sorts of reasons but scarcely thought about reef...
As far back as I can remember, I have always been fascinated by sharks. My father introduced me to the ocean through books, documentaries and diving, and whenever we would see sharks on a dive in the...
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...
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...
