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...
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...
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...
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...
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...
Researcher Aimee Ellison tests samples for DNA barcoding at the Gump Field Station on Moorea.
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...
About the IBRC The Indonesian Biodiversity Research Center (IBRC) was founded in June 2010 by a group of seven international research institutions to promote biodiversity stewardship in Indonesia...
Ichthyologist John R. Paxton of the Australian Museum studies freshly caught lanternfishes. Paxton was on the team that solved the whalefish mystery .
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...
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...
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...
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...
Students working on a marine genetics project at the Indonesian Biodiversity Research Center in 2011.
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...
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...
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...
