Scientists journey to the isolated island of Moorea on a quest to catalog every life form big enough to pick up with tweezers—from mountaintop to seafloor. Get up close and personal with researchers...
Two large coral trout ( Plectropomus leopardus ) swim through a coral reef on Taveuni Island in Fiji. Coral trout are highly desired fish for human consumption, and because of overfishing, are...
Tropical coral reefs—found in warm, clear, shallow waters—support a rich diversity of marine life, such as these sea bass in the Red Sea. Learn more in the Ocean Portal's Coral Reefs section .
There aren't any mummies or zombies buried under the seafloor: instead the ocean has its own terror from below, the bobbit worm ( Eunice aphroditois ). A couple inches wide and up to ten feet long,...
Smithsonian research assistant Anne Chamberlain and Marc Frischer from Skidaway Institute of Oceanography in Savannah, Georgia, stride through thick mud covered by algal mats in a mangrove pond at...
Watch a recorded webcast about the latest efforts in Greece to study and save the critically endangered Mediterranean monk seal. Centuries of human exploitation and habitat destruction have caused...
Around 100 million years ago, grass from land adapted to live and reproduce while submerged in seawater—the modern-day seagrasses. This sea invasion by land plants happened four separate times,...
The blue-spotted stingray ( Taeniura lymma ) doesn’t like to be covered in sand like other species of stingray do. Instead, it prefers to show off its beautiful blue spots and, to stay up to the best...
It's a pygmy seahorse ( Hippocampus bargibanti ), found in Indonesia's biodiverse Coral Triangle and one of the smallest seahorse species in the world! They can change colors like a chameleon to...
Welcome to Moorea, a tiny, isolated island in the middle of the vast Pacific. Moorea is 132 square kilometers (51 square miles) of tropical ecosystems – from jungle and wetlands to beaches and coral...
Researchers in Moorea use a variety of tools to collect organisms. Some are simple, everyday items like buckets and brushes, and some are…a little stranger. Here, two researchers use a “yabbie pump”...
The island of Moorea is a natural laboratory for scientists on a quest to catalog every life form big enough to pick up with tweezers. Head out into the field and watch as researchers use cutting-...
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...
Mangrove is the name for a tree—and also for a complex ecosystem—that bridges land and sea. There are around 70 species of mangrove trees (meaning trees that grow in a saline salt), but they are not...
