Slurping Shrimp near Moorea

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” to slurp...

Welcome to the Moorea Biocode Project

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 in...
Caribbean reef sharks swim over a coral reef in the Bahamas.

Swimming With Sharks

Lying in water only a foot deep, I watched the shark meander lazily through the mangrove, already exuding the confidence inherent of the supreme creature within its domain. It was hot here in Bimini,...

Hotspot of Biodiversity

This graph compares the crustacean biodiversity of coral reefs in Bali with two sites on the Great Barrier Reef (Heron and Lizard), Ningaloo Reef (NW Australia), Moorea, French Polynesia, Hawaii and the Line Islands...
On Moorea, an island in French Polynesia, researchers are striving to complete a biocode—a DNA catalog of every life form big enough to pick up with tweezers.

Scientists Catalog Life on the Island of Moorea

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...

Seagrass and Seagrass Beds

Seagrasses are found in shallow salty and brackish waters in many parts of the world, from the tropics to the Arctic Circle. Seagrasses are so-named because most species have long green, grass-like leaves. They...

Mangroves: Photos of Plants and Animals

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 can grow in salty water and soils),...

A Plague of Sea Stars

Scientists have been studying why populations of crown-of-thorns sea stars ( Acanthaster planci ) have mushroomed in recent decades. Coral reefs can suffer when the sea star's numbers explode; the echinoderm has a healthy...

Efforts to Protect the Critically Endangered Monk Seal

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 Mediterranean monk seals (...
