Marine scientists have discovered that the deepest oceans of the world would appear to be shark free. view more (2006-02-22)
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)
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)
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)
Satellite technology allows scientists to track warm sharks in cold polar seas
Electronic tags broadcasting from the dorsal fins of salmon sharks reveal that these top predators migrate from the glacial waters of Alaska to the warm seas off Hawaii. view more (2005-10-07)
Earth's Most Diverse Marine Life Found Off Indonesia's Papua Province
Two recent expeditions led by Conservation International (CI) to the heart of Asia's "Coral Triangle" discovered dozens of new species of marine life including epaulette sharks, "flasher" wrasse and reef-building coral, confirming the region as the Earth's richest seascape. view more (2006-09-21)
Study in Royal Society journal on possiblity of human organ regeneration
The interest of this article to the public centres on the discovery that non-functioning organs can be regenerated in adults by use of scaffolds alone (or scaffolds seeded with the subject's own epithelial cells). view more (2005-09-21)
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...

How marine reserves are giving coral reefs a helping hand
It may be no surprise that marine reserves protect the fish that live in them, but now scientists from the University of Exeter have shown for the first time that they could also help improve the health of coral reefs. view more (2006-01-06)
Ancient predator had strongest bite of any fish, rivaling bite of large alligators and T. rex
t could bite a shark in two. It might have been the first "king of the beasts." And it could teach scientists a lot about humans, because it is in the sister group of all jawed vertebrates. view more (2006-11-29)
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)
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)
Overfishing great sharks wiped out North Carolina bay scallop fishery
Fewer big sharks in the oceans led to the destruction of North Carolina's bay scallop fishery and inhibits the recovery of depressed scallop, oyster and clam populations along the U.S. Atlantic Coast, according to an article in the March 30 issue of the journal Science. view more (2007-03-30)
Scripps expedition provides new baseline for coral reef conservation
An ambitious expedition led by scientists at Scripps Institution of Oceanography at UC San Diego to a chain of little-known islands in the central Pacific Ocean has yielded an unprecedented wealth of information about coral reefs and threats from human activities. view more (2008-02-26)
Mixed dolphins and the impact of tourism
Dolphins off the coast of East Africa are exposed to a number of threats, like indirect catching, hunting, and environmental impact. In her dissertation at the Department of Zoology, Stockholm University, Sweden, Eva Stensland has studied behavioral ecology in Indo-Pacific bottlenose and humpback dolphins, off Zanzibar, Tanzania. For the last... view more... (2004-05-07)
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)
Overfishing large sharks impacts entire marine ecosystem, shrinks shellfish supply
Fewer big sharks in the oceans mean that bay scallops and other shellfish may be harder to find at the market, according to an article in the March 30 issue of the journal Science, tying two unlikely links in the food web to the same fate. view more (2007-03-30)
Evolving complexity out of 'junk DNA'
The study, published today in Proceedings of the National Academy of Sciences, USA, claims to have solved this scientific riddle by analysing the genomics of primitive living fishes such as sharks and lampreys and their spineless relatives, such as the sea squirts. view more (2008-02-12)
Conquest of land began in shark genome
When the first four-legged animals sprouted fingers and toes, they took an ancient genetic recipe and simply extended the cooking time, say University of Florida scientists writing in Wednesday's issue of the journal PLoS ONE. view more (2007-08-15)
