Forensics is a key tool for enforcing the laws and treaties that protect marine animals. Investigators in a recent case used DNA analysis to track down and convict sea turtle poachers. All seven...
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...
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 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...
Ichthyologist John R. Paxton of the Australian Museum studies freshly caught lanternfishes. Paxton was on the team that solved the whalefish mystery .
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...
Students working on a marine genetics project at the Indonesian Biodiversity Research Center in 2011.
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...
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...
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...
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...
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...
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...
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...
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...
