Researcher Aimee Ellison tests samples for DNA barcoding at the Gump Field Station on Moorea.
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...
Students working on a marine genetics project at the Indonesian Biodiversity Research Center in 2011.
Dr. Demian Chapman of the Institute for Ocean Conservation Science at New York’s Stony Brook University explains how DNA extraction from shark fins can identify the species of shark and where the...
A marine scientist performs a genetic analysis on a sample of deep-sea coral to find out if it is a known species or one new to science. Find out how ocean scientists study deep-sea corals in our...
Dr. Carole Baldwin is Curator of Fishes at the National Museum of Natural History. Read an interview with her about how she used DNA analysis and other tools to discover seven new species of fish in...
If you are a bird watcher you have probably heard of the Christmas Bird Count. The first one occurred on Christmas Day in 1900 at a variety of locations throughout North America, and it has since...
Ichthyologist John R. Paxton of the Australian Museum studies freshly caught lanternfishes. Paxton was on the team that solved the whalefish mystery .
We all know to avoid touching or eating oil (the fossil fuel variety that is). But after a coastal oil spill, avoiding oil can be difficult if you live near the sea or rely on it for protein or your...
So far, researchers have developed DNA barcodes to accurately identify 4,600 of the more than 29,000 known fish species. Atlantic cod is an economically important fisheries species. However, it's...
Doing scientific research on a ship isn't always easy. On top of having to live and sleep on a boat on the water, you have to fit all your scientific equipment onboard—and make sure it continues...
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...
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...
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...
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...
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...
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 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...
