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 around the world. Using genetic...
Starksia blennies, small fish with elongated bodies, generally native to...
Some fish you can fry up in the pan, no questions asked. Others require a...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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. 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...
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...
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...
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 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...
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...
Dr. Mahmood Shivji explains how shark DNA is used as evidence to prosecute shark fin poachers . What is shark finning? Find out here .
These cells are from a pygmy sperm whale in a laboratory culture dish. The red dyed cell are forming into fat cells after exposure to endocrine disruptors. GoMRI researchers are looking to see if oil...
