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”...
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...
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...
Shallow water coral reefs straddle the equator worldwide. The shallow coral reefs found in U.S. territorial waters are highlighted in purple in this map. More about coral reef ecosystems can be found...
This slug caterpillar ( Acharia horrida ), which will eventually metamorphosize into a very plain brown moth, has stinging spines that are very nasty to rub up against. Although the slug caterpillar...
Monk seals -- the only completely tropical species of seal in the world -- are in trouble. Centuries of human exploitation and habitat destruction have caused the remaining populations of...
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-...
This guineafowl moray ( Gymnothorax meleagris ) is one of about 200 species of moray eels found in tropical and subtropical coral reefs . Moray eels are a type of bony fish. Many species, like this...
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...
How do you explain a scientific paper in three minutes or less? What if you were being judged by a bunch of middle-schoolers in classrooms around the world… and you only had a month to do it? The...
Dr. Candy Feller is framed by the roots of a mangrove tree on Panama’s Pacific coast. Mangrove trees grow particularly large in this area. More about mangroves can be found in our Mangroves featured...
The Eastern cleaner-clingfish ( Cochleoceps orientalis ) has its job title in its name: “cleaner.” They prove invaluable to larger fish by removing parasites to keep the larger fish clean and healthy...
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...
The rich colors of emperor angelfish make them a vibrant version of royalty. They are curious fish that will come and greet their human visitors. However this unique coloring is not shared with all...
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...
One of the first signs of a sick coral reef is seaweed creeping across the corals, stealing their precious sunny real estate. Healthy corals, however, aren't completely hopeless: in some reefs, small...
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...
