Millions of years ago, the "smasher" mantis shrimp, one of nature's feistiest predators, figured out a similar way to protect the hammer-like club it uses to pulverize prey with incredible speed and force.In research published today in Advanced Materials, a group of researchers led by UC Riverside's David Kisailus has identified a unique structure that wraps around the mantis shrimp's club to protect it from self-inflicted damage as it crushes hard-she

in harm's way: wolves may not risk 'prey switching' ecologists say

Ecologists have long observed predators pursue disproportionately more of a plentiful prey species, and less of scarce prey, but change to the latter if it becomes relatively more abundant. Known as "prey switching," this phenomenon is ecologically important, because it helps to stabilize wildlife populations. But what if the more abundant prey is more dangerous?

drill holes in fossil shells point to bigger predators picking on small prey

The drill holes left in fossil shells by hunters such as snails and slugs show marine predators have grown steadily bigger and more powerful over time but stuck to picking off small prey, rather than using their added heft to pursue larger quarry, new research shows.The study, published today in Science, found the percent of shell area drilled by predators increased 67-fold over the past 500 million years, suggesting that the ratio of predatory driller size and tough-shelled prey increased substantially. The study's authors say the widening gap could be caused by greater numbers and better nutritional value of prey species and perhaps to minimize predators' vulnerability to their own enemies."These drill holes track the rise of bullies: bigger, stronger predators hunting the same size prey

understanding how slow predators catch faster prey could improve drone tactics

(Phys.org)—Since a gazelle can run faster than a lion, how do lions ever catch gazelles? A new model of predator-prey interaction shows how groups of predators use collective chasing strategies, such as cornering and circling, to pursue and capture faster prey. Without this tactical collaboration, the predators would have no chance of catching these prey.

The results shed light on dragonflies' position in natural food webs with an unprecedented specificity. Dragonflies and damselflies, i.e. the odonates, are numerous and quite large insects.

the remarkable hunting ability of the robber fly

Unlucky fruit fly did not escape the keen eyes and aerial virtuosity of Holcocephala, who now sits on a stick consuming its prize. Credit: Sam FabianA small fly the size of a grain of rice could be the Top Gun of the fly world, with a remarkable ability to detect and intercept its prey mid-air, changing direction mid-flight if necessary before sweeping round for the kill.
The robber fly Holcocephala is a relatively small fly - at 6mm in length, it is similar in size of the average mosquito. Yet it has the ability to spot and catch prey more than half a metre away in less than half a second - by comparison to its size, this would be the equivalent of a human spotting its prey at the other end of a football pitch. Even if the prey changes direction, the predator is able to adapt mid-air an

ants rescue their injured

The African Matabele ants (Megaponera analis) are widespread south of the Sahara and are a specialised termite predator. Two to four times a day, the ants set out to hunt prey. Proceeding in long files, they raid termites at their foraging sites, killing many workers and hauling the prey back to their nest.

how bacteria hunt other bacteria

A bacterial species that hunts other bacteria has attracted great interest as a potential living antibiotic, but exactly how this predator tracks down its prey has not been clear. A study published March 28 in Biophysical Journal sheds light on this question, revealing that the bacterial predator Bdellovibrio bacteriovorus (BV) homes in on its target by taking advantage of fluid forces generated by its own swimming movements and those of its prey. These hydrodynamic flow fields bring the bacteria in close proximity, giving BV a greater chance of successful attack.
"Despite having been discovered over 50 years ago, very little is known about how the bacterial predator BV locates its bacterial prey," says co-senior study author Steve Pressé of Arizona State University. "Understanding how B

african lions face same threats as extinct ice age ancestors

Newly published in the journal Ecography, the study shows that the wildlife that went extinct during the period, including the sabre-toothed cat, cave and American lions and the American cheetah, lost the greatest proportion of their prey. Big cats today face the same challenges and food shortages as their ancestors and without immediate action, the same fate could likely be inevitable. Led by scientists from the Universities of Sussex, Oxford's Wildlife Conservation Research Unit (WildCRU), Aarhus and Goteborg, the team assessed several Ice Age extinction factors and whether they could be applied to big cat species populations today. Using a new global database of felid diets called FelidDiet, the team uncovered the cause of extinction of several Ice Age giants. The findings show that if
