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...
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...
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...
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...
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...
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. 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...
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...
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...
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...
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...
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...
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...
Ichthyologist John R. Paxton of the Australian Museum studies freshly caught lanternfishes. Paxton was on the team that solved the whalefish mystery .
Researcher Aimee Ellison tests samples for DNA barcoding at the Gump Field Station on Moorea.
Good real estate is hard to find. This is as true underwater as it is on land. So when Smithsonian scientist Dr. Matthieu Leray built 18 potential homes for undersea creatures living on oyster reefs...
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...
