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...
Ichthyologist John R. Paxton of the Australian Museum studies freshly caught lanternfishes. Paxton was on the team that solved the whalefish mystery .
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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. 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...
