Shark attack worries? Driving to the beach is more deadly
Which is more likely to happen-you being in a car wreck or being bitten by a shark? Those who answered that cars are greater killers win a free trip to the beach view more (2005-06-30)
Shark skin saves naval industry money
Covering ship hulls with artificial shark skin could help ships sailing smoothly. The growth of marine organisms such as barnacles on ship hulls is a major cause of increased energy costs in the naval industry. Shark skin offers a structural design that prevents this so called 'bio-fouling'. view more (2005-07-18)
The Secret of the shark's sneaky speed is revealed
Many shark species, including the great white and mako, swim at speeds greater than their morphology should allow. Dr. Adam Summers (University of California) has discovered they achieve this speed by changing the stiffness of their body by pressurising their thick, inflexible skin. "This study could help answer questions about the evolution... view more... (2003-03-31)
World shark attacks dipped in 2005, part of long-term trend
Assertive and even aggressive human behavior could explain why shark attacks worldwide dipped last year, continuing a five-year downward trend in close encounters with the oceanic predators. view more (2006-02-14)
Sharks in danger
There are 370 species of shark, each with their own particular habitats and behaviours. Most sharks are slow to reproduce and do not have large numbers of young. They are therefore particularly sensitive to predation or large losses. Caught as accidental by-catch (estimated at 3000 per day), sharks are also fished for their fins (for food),... view more...

Declining sharks
The transformation of terrestrial and coastal ecosystems by humans is well known, but only recently have the impacts of anthropogenic forces in the open ocean been recognized. In particular, intense exploitation by industrial fisheries is rapidly changing oceanic ecosystems by drastically reducing populations of many marine species. For most... view more... (2004-02-05)
Elephant shark genome sequence leads to discovery of color perception in deep-sea fish
The elephant shark, a primitive deep-sea fish that belongs to the oldest living family of jawed vertebrates, can see color much like humans can. view more (2009-03-18)
Human deaths from shark attacks hit 20-year low last year
Fatal shark attacks worldwide dipped to their lowest levels in two decades in 2007 with the sole casualty involving a swimmer vacationing in the South Pacific, according to the latest statistics from the University of Florida. view more (2008-02-13)
UF study: World shark attacks rise slightly but continue long-term dip
Shark attacks edged up slightly in 2006 but continued an overall long-term decline as overfishing and more cautious swimmers helped take a bite out of the aggressive encounters, new University of Florida research finds. view more (2007-02-14)
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)
Photo-monitoring whale sharks
Up to 20 meters long and weighing as much as 20 tons, its enormous size gives the whale shark (Rhincodon typus) its name. Known as the 'gentle giant' for its non-predatory behavior, this fish, with its broad, flattened head and minute teeth, eats tiny zooplankton, sieving them through a fine mesh of gill-rakers. view more (2007-12-26)
UT Biologist Researches Sharks' "Bite Force."
While sharks instill fear in beachgoers worldwide, they instill a deep sense of curiosity in UT assistant professor and shark expert Dan Huber. view more (2007-08-24)
Whale shark protected in new marine conservation project
Dr Callum Roberts of the Environment Department at the University of York has been awarded £130,000 by the UK Darwin Initiative fund to work with the Belize Department of Fisheries, conservation organisations and local communities on conservation strategies for migratory species such as the threatened whale shark. Many marine migratory... view more... (2000-03-09)
Endangered sawfish focus of national collection and recovery efforts
The University of Florida, keeper of the world's shark attack records, is also now overseeing a national records collection for another toothy marine predator: the sawfish. view more (2008-12-02)
Scientists Conduct Shark Survey off U.S. East Coast
Sandbar, dusky and tiger sharks are among dozens of shark species living in the coastal waters off the U.S. East Coast. Little is known about many of the species, but a survey begun nearly 25 years ago is helping scientists and fishery resource managers to monitor shark populations and their role in marine ecosystems. view more (2009-08-14)
Oceans are 70% shark free
Marine scientists have discovered that the deepest oceans of the world would appear to be shark free. view more (2006-02-22)
Geographic profiling applied to track hunting patterns of white sharks in South Africa
Predation is one of the most fundamental and fascinating interactions in nature, and sharks are some of the fiercest predators on Earth. view more (2009-06-22)
Can Certain Metals Repel Sharks from Fishing Gear?
Sharks in captivity avoid metals that react with seawater to produce an electric field, a behavior that may help fishery biologists develop a strategy to reduce the bycatch of sharks in longline gear. view more (2008-04-23)
Heart attacks are not all bad
New research shows that heart attack survivors and their partners actually feel they benefited from the attack. view more (2004-08-23)
Great white's mighty bite revealed
Using sophisticated computer modelling techniques they have also calculated that the bite force of the great white's extinct relative, the gigantic fossil species Carcharodon megalodon (also known as Big Tooth) is the highest of all time, making it arguably the most formidable carnivore ever to have existed. view more (2008-08-04)
