UIC biologists use DNA to study migration of threatened whale sharks
Whale sharks -- giants of the fish world that strike terror only among tiny creatures like the plankton and krill they eat -- are imperiled by over-fishing of the species in parts of its ocean range. view more (2009-04-08)
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)
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...

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)
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)
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)
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)
Unveiling the underwater ways of the white shark
It's hard to study a creature when you only catch fleeting glimpses of it. Up until recently, that was one of the big stumbling blocks for marine biologists and ecologists, but advances in electronic tracking technology have allowed them to peer farther across, and deeper under, the surface of the oceans than ever before. view more (2008-02-19)
Deep-sea sharks wired for sound
Deep-sea sharks have been tagged and tracked and their habitats precisely mapped in world-first research to test the conservation value of areas closed to commercial fishing. view more (2008-04-16)
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)
Tags reveal white sharks have neighborhoods in the north Pacific, say Stanford researchers
The white shark may be the ultimate loner of the ocean, cruising thousands of miles in a solitary trek, but a team of researchers has discovered that the sharks have maintained such a consistent pattern of migration that over tens of thousands of years the white sharks in the northeastern Pacific Ocean have separated themselves into a population... view more...

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)
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)
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)
Armour-plated fish and the evolution of dentists
The discovery of small spikes lining the mouths of primitive fossil fish reveal surprising new details about how early animals fed. New research published today in a Royal Society paper sheds light on how teeth evolved. Primitive fish did not have jaws or fins but were covered in rigid bony scales and resembled small armour-plated submarines. Dr... view more... (2002-01-07)
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)
New species of ghostshark from California and Baja California
New species are not just discovered in exotic locales-even places as urban as California still yield discoveries of new plants and animals. view more (2009-09-22)
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)
New research shows sharks use their noses and bodies to locate smells
Sharks are known to have a keen sense of smell, which in many species is critical for finding food. However, according to new research from Boston University marine biologists, sharks can not use just their noses to locate prey; they also need their skin - specifically a location called the lateral line. view more (2007-05-30)
