Marine Biology Mystery Solved: Function of "Unicorn" Whale's 8-foot Tooth Discovered
Today, Harvard School of Dental Medicine (HSDM) researcher Martin Nweeia, DMD, DDS, answers a marine science question that has eluded the scientific community for hundreds of years: why does the narwhal, or "unicorn," whale have an 8-foot-long tooth emerging from its head, and what is its function? view more (2005-12-14)
The Arctic and Global Warming
A warmer Arctic Ocean may mean less food for the birds, fish, and baleen whales and be a significant detriment to that fragile and interconnected polar ecosystem, and that doesn't bode well for other ocean ecosystems in the future. view more (2006-02-21)
How ancient whales lost their legs, got sleek and conquered the oceans
When ancient whales finally parted company with the last remnants of their legs about 35 million years ago, a relatively sudden genetic event may have crowned an eons-long shrinking process. view more (2006-05-23)
Warbling Whales Speak a Language All Their Own
The songs of the humpback whale are among the most complex in the animal kingdom. Researchers have now mathematically confirmed that whales have their own syntax that uses sound units to build phrases that can be combined to form songs that last for hours. view more (2006-03-22)
Monitoring Baleen Whales with Autonomous Underwater Vehicles
Like robots of the deep, autonomous underwater vehicles, or AUVs, are growing in number and use in the oceans to perform scientific missions ranging from monitoring climate change to mapping the deep sea floor and surveying ancient shipwrecks. view more (2006-02-22)
Early whales gave birth on land
Two newly described fossil whales--a pregnant female and a male of the same species--reveal how primitive whales gave birth and provide new insights into how whales made the transition from land to sea. view more (2009-02-05)
Underwater listening devices yield discoveries about endangered large whales
Why whales emit their characteristic calls remains largely a biological mystery, but listening for the distinctive underwater sounds provides a valuable way to track the movements of endangered large whales. view more (2006-01-03)
Reef Sharks Threatened by Overfishing
A study by Australian scientists has warned that coral reef shark populations on the Great Barrier Reef are in the midst of a catastrophic collapse. view more (2006-12-06)
Antarctic krill provide carbon sink in Southern Ocean
New research on Antarctic krill (Euphausia superba), a shrimp-like animal at the heart of the Southern Ocean food chain, reveals behaviour that shows that they absorb and transfer more carbon from the Earth's surface than was previously understood. view more (2006-02-07)
Yale researchers find environmental toxins disruptive to hearing in mammals
Yale School of Medicine researchers have new data showing chloride ions are critical to hearing in mammals, which builds on previous research showing a chemical used to keep barnacles off boats might disrupt the balance of these ions in ear cells. view more (2006-04-12)
New theory -- universal intelligence on animals and plants
Here it is proposed that life in all its variety is full of sensation and creates a complicated web of interaction with its surroundings. Mammals, birds and even fish mourn for a lost love. Single-celled organisms carry out tasks that are surprisingly complicated. We can demonstrate sensitivity in microscopic organisms, while plants emerge as... view more... (1999-03-25)
FSU scientist warns North Atlantic right whale facing extinction
The North Atlantic right whale's future looks grim if the current mortality rates continue, according to Florida State University assistant professor of oceanography Douglas Nowacek and a group of fellow scientists from across the nation. view more (2005-07-25)
Beaked Whales Perform Extreme Dives to Hunt Deepwater Prey
A study of ten beaked whales of two poorly understood species shows their foraging dives are deeper and longer than those reported for any other air-breathing species. view more (2006-10-23)
Parachuting allows krill to eat and run
Antarctic researchers have recorded a novel behavior in krill that may help regulate greenhouse gases. Antarctic krill, one of the largest animal resources on Earth, parachute into the deeper layers of the ocean many times a night and sequester large amounts carbon in the process. view more (2006-02-07)
Genetics links whale to two different ocean basins
For the first time ever, a genetic study has followed a single humpback whale from one ocean basin to another, adding to traditional notions of the migratory patterns of these majestic marine mammals in the process. view more (2005-08-18)
Tracking sperm whales and jumbo squid
The sperm whale and its large prey, the jumbo squid, are among the deepest divers in the ocean, routinely reaching depths of 3,000 feet or more. view more (2007-03-09)
ROV discovers Antarctic seafloor fauna
Remotely Operated Vehicles (ROV) remain an efficient technology to uncover the secrets of Antarctic seafloor fauna. As a precursor to the International Polar Year 2007/2008, the current Polarstern expedition conducted by the Alfred Wegener Institute for Polar and Marine research releases short seafloor video clips taken by ROV only a few hours... view more...

Saving endangered whales at no cost
By comparing the productivity of lobster fishing operations in American and Canadian waters of the Gulf of Maine, researchers have identified ways in which cost-saving alterations in fishing strategies can substantially reduce fishing-gear entanglements of the critically endangered North Atlantic right whale. view more (2007-01-09)
El Nino events affect whale breeding
A thirty-year study by an international team of scientists found a strong relationship between breeding success of whales in the South Atlantic and El Nino in the western Pacific. view more (2006-01-11)
Leading scientists rank endangered dolphins, porpoises most in need of immediate action
Leading marine scientists for the first time have assessed dolphin and porpoise populations around the world which are severely threatened by entanglement in fishing gear and recommended nine urgent priorities for action in a report commissioned by the World Wildlife Fund. These nine projects highlight species threatened by bycatch that will most... view more... (2005-06-09)
