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 more than 100 years. It would...
Another common species of sargassum shrimp, Leander tenuicornis (...
Some fish you can fry up in the pan, no questions asked. Others require a...
Dr. Mahmood Shivji explains how shark DNA is used as evidence to prosecute shark fin poachers . What is shark finning? Find out here .
Even on an early winter morning, it was sunny and warm in southern Florida. This was great because, regardless of the weather, Dr. Jon Norenburg and I were going to walk chest-deep into the water to...
Another common species of sargassum shrimp, Leander tenuicornis (Palaemonidae) can be spotted by its long transparent claws or "chelae". Very similar shrimp are found in near shore habitats all...
This piece of pocillopora, or cauliflower coral , would normally have a rigid outer skeleton, but researchers dissolved it to expose the coral’s tissue and take a sample for DNA analysis. Read more...
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...
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...
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...
This month, our friends at National Geographic are featuring Smithsonian's own bio-scavenger, Chris Meyer and his work in one of our favorite places: Moorea , French Polynesia. In a beautiful meld of...
Scientists on the tiny island of Moorea, in the Pacific, are gathering one of every life form large enough to pick up with tweezers. They're on a quest to build a detailed catalog of the entire...
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...
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...
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...
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...
The island of Moorea is a natural laboratory for scientists on a quest to catalog every life form big enough to pick up with tweezers. Head out into the field and watch as researchers use cutting-...
By Emily Frost You’ve probably heard of genetics—you can now swab your mouth and use DNA to find information about your ancestry going back hundreds to thousands of years or see if you have a...
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...
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...
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...
