In marshlands along the coast of the Gulf of Mexico, it's easy to hear the sharp, buzzing calls of seaside sparrows ( Ammodramus maritimus )—even if they can be hard to spot. These five-inch, brown...
Starksia blennies, small coral reef fish with elongated bodies, have been well-studied for more than 100 years. But things are not always what they seem when it comes to fish. Using genetic analysis...
Starksia blennies, small coral reef fish, have been well-studied for more than 100 years. But Smithsonian scientists discovered that what were thought to be three species of the fish are actually 10...
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...

Using genetic analysis combined with traditional study of morphology, Smithsonian scientist Dr. Carole Baldwin and her team discovered that what were thought to be three species of the fish are...
Dr. Carole Baldwin never expected to find seven new species of fish among the Starskia blennies she was studying at the Smithsonian's National Museum of Natural History. "My research team was using...
Some fish you can fry up in the pan, no questions asked. Others require a bit of research. Case in point: the puffer fish. Commonly known as fugu, some species contain toxins more deadly than cyanide...
Researchers with the Smithsonian's Deep Reef Observation Project (DROP) collected this sea toad, Chaunax pictus , off the coast of Honduras in 2011. The team is trying to collect sea toads from...
It's illegal to hunt threatened species such as the Dusky shark, but still tens of millions of sharks are taken each year for their fins—in high demand as a delicacy in China. Inside his laboratory...
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...
