Human infants often already resemble their parents. Visitors coo, "Oh, she has your eyes," or "He is the spitting image of his father." But what if the infant (or in this case, the larva) looked...
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...
Band-rumped Storm-petrels ( Oceanodroma castro ) are quite a bit larger and heavier than Wilson's storm petrels, but share their amazing sense of smell, which they use to find food that may be miles...
Students working on a marine genetics project at the Indonesian Biodiversity Research Center in 2011.
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...
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...
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...
Microbes are some of the most important organisms in the sea. These miniscule organisms provide an important link in the food web between the dissolved nutrients in the ocean and larger organisms...
Researcher Aimee Ellison tests samples for DNA barcoding at the Gump Field Station on Moorea.
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...
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...
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...
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...
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...
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...
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...
