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 reefs – with no major landmasses for thousands of miles. While it may look like the perfect vacation...

In 2003, a team of Japanese scientists analyzed the DNA of tapetails and whalefish. The results suggested that these two very different looking fishes were almost identical in one specific gene. But more clues were needed. An international team of marine biologists took a closer look at specimens...

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 barcoding to match larval stages of reef fishes to adults," she said. But when comparing the DNA of...

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. The Indo-Pacific puffer Lagocephalus cf. suezensis (pictured here) is among the more toxic....

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 the field and see how they combine high-tech equipment and old-fashioned elbow grease to tackle...

Dr. Mahmood Shivji of the Guy Harvey Research Institute and Save Our Seas Shark Center sampling a confiscated shark fin for DNA analysis. He can determine the species for hundreds of shark fins using a method called DNA barcoding. This data can be used to crack down on the illegal fishing of sharks.

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 combined with traditional study of morphology, Smithsonian scientists recently discovered that what...

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 actually 10 distinct species from the Caribbean. The discovery of new Starksia blennies, small coral reef...

Starksia blennies, small fish with elongated bodies, generally native to shallow to moderately deep rock and coral reefs in the western Atlantic and eastern Pacific oceans, have been well-studied for more than 100 years. It would have been reasonable to assume that there was little about the group...
