SHOCKING! Crabs Really Do Feel Pain
2013-01-17 08:36:00

Brett Smith for redOrbit.com - Your Universe Online Most cultures value the humane treatment and slaughter of their livestock, and now those same standards should be applied to their seafood, according to a new behavioral study published in the Journal of Experimental Biology. The study, from Queen's University Belfast professors Bob Elwood and Barry Magee, exposed common shore crabs to electrical shocks and found those crabs responding to the shocks in a way consistent with...

New New Crab Species Named In Honor Of Its Discoverer
2012-11-27 13:06:16

April Flowers for redOrbit.com - Your Universe Online Imagine the surprise if you learned that a new species had been named after you. That's exactly what happened to Dr. Christopher Tudge of American University recently as he was reading a copy of the journal, Zootaxa. Finding out after-the-fact is fairly standard practice in the highly formalized naming ritual of new species, it seems. The new species, Aeropaguristes tudgei, is a type of hermit crab that Tudge recently...

Using GPS To Monitor Trekking Behavior In Crabs
2012-11-15 17:25:03

Alan McStravick for redOrbit.com - Your Universe Online We all know that crabs walk sideways--it´s because that´s the way their legs bend. This side-walking trait allows them to move quickly into and out of small holes and crevasses to escape potential threats. So, we know how and why they walk. We just don´t necessarily know where they walk. That is, until now. Scientists this week from the Zoological Institute at the University of Greifswald, in cooperation with...

Beware Of House-Jacking Hermit Crabs
2012-10-27 06:28:35

redOrbit Staff & Wire Reports - Your Universe Online In their search for larger homes, land-based hermit crabs will socialize with their fellow decapods only to force them out of their shells and claim it for their own, researchers from the University of California-Berkeley have discovered. While all types of hermit crabs will claim abandoned snail shells as their own, only the terrestrial types of these crustaceans hollow them out and remodel the shells. This allows them to...

Death March Recorded In Fossil
2012-09-10 04:27:43

Brett Smith for redOrbit.com - Your Universe Online An unusually complete fossil unearthed in Bavarian Germany was found to depict the tragic last moments of a prehistoric horseshoe crab as it stumbled for its life over 150 million years ago. The crab´s fossilized track, which is over 31 feet in length, displays both the beginning and end of its death march that was the result of the arthropod falling into a stagnant lagoon, according to a recent report published in the journal...

Discovery Of The Week: Purple Philippine Freshwater Crabs

The Philippines is the setting for the latest spectacular discovery: Four new species of crabs, most of which have purplish shells and live in lowland-forest ecosystems, discovered by a team of German scientists, reports National Geographic. The four new discoveries, all of which are found only on the island of Palawan, were co-discovered and described by Hendrik Freitag of Germany´s Senckenberg Museum of Zoology. “In the Aqua Palawana research program I am head of, we have...

Logic Gate Study Analyzes Crab-Inspired Computing
2012-04-16 04:05:12

A team of scientists from Japan and the UK have built a computer that is inspired by a most unusual source -- the real-life movements and swarming behavior of soldier crabs, PCMag.com's David Murphy and Wired UK's Olivia Solon reported over the weekend. The researchers, who are affiliated with Kobe University and the University of the West of England (UWE), devised the system for defining computer logic based on the crabs' movements and their "natural tendency for swarming," which...

As any comic book lover knows, when superheroes band together the bad guys fall harder. The strength that comes in numbers is greater than the sum of its parts. The same holds true, researchers have recently learned, when different species of crabs (genus Trapezia) and snapping shrimp (Alepheus lottini) in the central Pacific band together to defend their coral homes from hungry seastars. In these frequent conflicts "one-plus-one doesn't always equal two, sometime it is more," explains...

How Crabs Avoid Getting Eaten
2011-11-26 05:08:41

Despite their simple compound eyes crabs have evolved a smart way to tell the difference between friend and foe, new scientific research has revealed. Scientists from The Vision Centre have found that fiddler crabs quickly learn to recognize if an approaching creature is a threat, a mate or a harmless passer-by - according to its direction of approach. “Fiddler crabs have extremely poor sight, with no depth perception and no ability to see in detail,” says Ms Chloe...

Researchers have found that a species invasion that starts at the upstream edge of its range may have a major advantage over downstream competitors, at least in environments with a strong prevailing direction of water or wind currents. Scientists from the University of Georgia, University of New Hampshire, Smithsonian Environmental Research Center and University of Vermont studied populations of European green crab, Carcinus maenas. The species was introduced to the East Coast of North...

The Halloween Crab (Gecarcinus quadratus or Gercarcinus ruricola), also known as the moon crab, should not be confused with the Halloween hermit crab. They dig burrows in rainforest habitat and are native to Central America. It lives in the forest at least some of its adult life. They have lungs that need to be moist all the time. If not, they could dry out and die. The Halloween crab is very territorial and will fight back if threatened. Photo Copyright and Credit
