Marine parasites may be small in size, but they can be present in very high numbers and put together can weigh even more than all the top predators in an estuary or bay ecosystem! They play an...
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 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...
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...
It’s hard not to identify with penguins as they waddle about upright on land, clad in their tuxedo-like plumage. In their crowded breeding colonies, they squabble with and show off to their neighbors...
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...
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...
I became interested in weather phenomena when I took physics in high school. At the time, I just wanted to understand how various things in nature worked. Unfortunately, most information about...
Scientists don’t often get the opportunity to travel through time. But nestled among the beautiful coral reefs of Papua New Guinea (PNG) is a place that provides a glimpse today of what could be the...
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...
Top predators along the California coast are having a rough year. Recently starving sea lions have showed up on California beaches and are clamoring for fish at the mouth of Oregon's Columbia River...
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...
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...
In 1872, the United States did something remarkable. We set aside one of our greatest natural treasures, Yellowstone National Park , for future generations to enjoy and appreciate. The logic was...
The Kemp’s ridley is a “riddler” among sea turtles . Although the species was initially recognized in 1880, scientists didn't know where it nested until 80 years later, when a film documenting about...
Shooting seascapes often involves hiking on very delicate rock formations near tidepools and reefs full of plant and marine life. The photographer has to be very careful when walking on these rocks,...
It blew in for two solid days: a flotilla of plastic forks, soda bottles, rubber gloves, and other refuse. I tried to pick everything up off the beach, but when I turned around, you couldn’t tell...
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...
