Creeping crinoids! Sea lilies crawl to escape predators, new video shows
With their long stalks and feathery arms, marine animals known as sea lilies look a lot like their garden-variety namesakes. view more (2005-10-17)
Penn Biologists Demonstrate that Size Matters-in Snail Shells
A team of biologists at the University of Pennsylvania has completed a research study begun in 1915 and determined that a snail making its home in the northwest Atlantic Ocean around Mount Desert Island, Me., has experienced a dramatic increase in the size of its shell during less than a century, providing a clear illustration of how fast and... view more...

Squid 'sight': Not just through eyes
It's hard to miss the huge eye of a squid. But now it appears that certain squids can detect light through an organ other than their eyes as well. view more (2009-06-02)
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)
Novel living system recreates predator-prey interaction
The hunter-versus-hunted phenomenon exemplified by a pack of lionesses chasing down a lonely gazelle has been recreated in a Petri dish with lowly bacteria. view more (2008-04-14)
Marine phytoplankton changes form to protect itself from different predators
In a paper published June 11 in the online version of Proceedings of the National Academy of Sciences, researchers report the first evidence that a common species of saltwater algae - also known as phytoplankton - can change form to protect itself against attack by predators that have very different feeding habits. view more (2007-06-18)
Flips, flops and cartwheels
Geckos and other lizards have long been known for their incredible ability to shed their tails as a decoy for predators, but little is known about the movements and what controls the tail once it separates from the lizard's body. view more (2009-09-09)
Squirrels Use Snake Scent
California ground squirrels and rock squirrels chew up rattlesnake skin and smear it on their fur to mask their scent from predators, according to a new study by researchers at UC Davis. view more (2007-12-20)
Winter Flounder On The Fast Track To Recovery
Winter flounder - sold in markets as flounder or lemon sole - in the Gulf of Maine went into serious decline in the 1980s, taking with it a major commercial and recreational fishery. view more (2007-04-17)
Great tits can reduce caterpillar damage in apple orchards
The potential contribution of vertebrate predators to biological control in orchards has been largely overlooked to date. A few studies have shown that birds reduce numbers of pests, but data are scarce on the effects on the pattern or timing of damage. Consequently, the practical value of birds as biocontrol agents remains unclear. view more (2002-11-26)
500 million years of errors: Brachiopod shells record shadow of arms race in ancient oceans
A study of fossils from the Paleozoic Era, collected across the world, reveals that ancient brachiopods were little bothered by predators. However, the rare predation traces left on brachiopod shells by unknown assailants coupled with a subtle increase in their frequency through time may be the shadows on the wall that show killers were in the... view more...

When evolution is not so slow and gradual
What's the secret to surviving during times of environmental change? Evolve-quickly. view more (2009-06-03)
Scientist's persistence sheds light on marine science riddle
When he started compiling an online database of seashells 15 years ago, Dr. Gary Rosenberg did not envision that his meticulous record-keeping would eventually shed light on a 40-year-old evolutionary debate. view more (2006-09-08)
Lionfish decimating tropical fish populations, threaten coral reefs
The invasion of predatory lionfish in the Caribbean region poses yet another major threat there to coral reef ecosystems - a new study has found that within a short period after the entry of lionfish into an area, the survival of other reef fishes is slashed by about 80 percent. view more (2008-07-21)
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)
Bizarre walking bat has ancient heritage
A bizarre New Zealand bat that is as much at home walking four-legged on the ground as winging through the air had an Australian ancestor 20 million years ago with the same rare ability, a new study has found. view more (2009-07-29)
U of Minnesota-led study finds that hunters are depleting lion and cougar populations
Sport hunters are depleting lion and cougar populations as managers respond to demands to control predators that threaten livestock and humans, according to a study published in the June 17 issue of PLoS ONE. view more (2009-06-18)
MU researchers reveal communication tactics used by sexual predators to entrap children
A child's innocence and vulnerability presents a target for a sexual predator's abusive behavior. University of Missouri researchers are beginning to understand the communication process by which predators lure victims into a web of entrapment. This information could better equip parents and community members to prevent, or at least interrupt, the... view more... (2008-04-18)
Wolf reintroduction proposed in Scottish Highland test case
Researchers are proposing in a new report that a major experiment be conducted to reintroduce wolves to a test site in the Scottish Highlands, to help control the populations and behavior of red deer that in the past 250 years have changed the whole nature of large ecosystems. view more (2009-07-21)
Pendulums, predators and prey: The ecology of coupled oscillations
Connect one pendulum to another with a spring, and in time the motions of the two swinging levers will become coordinated. view more (2006-12-04)
