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...
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...
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...
My father once told me that the world is divided into two kinds of people: those who believe that the world is divided into two kinds of people and those who don’t. Wherever you come down on this...
Cashes Ledge is a wild, special place in the heart of the Gulf of Maine. This underwater mountain range is home to a great diversity of life, with colors typically associated with a coral reef rather...
Ever since fourth grade I’ve wanted to explore the creatures and landscapes of the deep ocean in a submersible. It took awhile, but I finally got my chance this summer as part of the Deep Reef...
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...
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...
You are not alone if you don’t know what forams (short for foraminifera) are, so let’s start with the basics. Simply put, forams are single-celled organisms related to the familiar amoeba that...

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...
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...
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...
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...
The open ocean is surprisingly barren to the naked eye. Every now and again you will encounter a school of fish and their attendant predators, but most of the life that you find is gathered around...
As I readied myself and my camera for a dive in Yellowstone Lake, the largest body of water in Wyoming’s Yellowstone National Park, I thought I was on top of my game. I had recently specialized in...
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...
