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 .
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
