Invasions of voracious predatory crabs due to global warming could threaten the unique continental-shelf ecosystems of Antarctica, according to newly published findings. "King crabs are ecologically important predators and form the basis of economically significant commercial fisheries," said Dr Sven Thatje, an evolutionary ecologist at the University of Southampton's School of Ocean and Earth Science (SOES), which is based at the National Oceanography Centre in Southampton. Thatje and...

Sensor uses frog peptides to test for drug and medical device contamination Princeton engineers have developed a sensor that may revolutionize how drugs and medical devices are tested for contamination, and in the process also help ensure the survival of two species of threatened animals. To be fair, some of the credit goes to an African frog. In the wild, the African clawed frog produces antibacterial peptides -- small chains of amino acids -- on its skin to protect it from infection....

Having survived for more than 400 million years, the horseshoe crab is now under threat "“ primarily due to overharvest and habitat destruction. However, climatic changes may also play a role. Researchers from the University of Gothenburg reveal how sensitive horseshoe crab populations are to natural climate change in a study recently published in the scientific journal Molecular Ecology. The horseshoe crab is often regarded as a living fossil, in that it has survived almost unchanged...

Decline may affect at-risk shorebirdsA distinct decline in horseshoe crab numbers has occurred that parallels climate change associated with the end of the last Ice Age, according to a study that used genomics to assess historical trends in population sizes.  The new research also indicates that horseshoe crabs numbers may continue to decline in the future because of predicted climate change, said Tim King, a scientist with the U.S. Geological Survey and a lead author on the new study...

In trying to predict how species will respond to climate change caused by global warming, researchers and scientists are turning to comparative physiology, a sub-discipline of physiology that studies how different organisms function and adapt to diverse and changing environments. By comparing different species to each other, as well as to members within a species that live in different environments, researchers are learning which physiologic features establish environmental optima and...

In 1988, a mysterious invader washed upon the New Jersey shore. The Asian shore crab likely arrived in ballast from commercial ships, and it found its new home to be quite agreeable. More than two decades later, the crab, Hemigrapsus sanguineus, has expanded its range along the Atlantic coast northward to Maine and southward to North Carolina. Its numbers continue to expand, and wildlife biologists have found them in greater densities along New England's cobbled shores. Another tale of an...

Previously unknown group behaviors lead to better housing for all Everyone wants to live in the nicest possible house, ideally with regular upgrades. A recent study by biologists at Tufts University's School of Arts and Sciences and the New England Aquarium reveals that hermit crabs may locate new and improved housing using previously unknown social networking skills. The scientists combined field studies, lab experiments and computer models to uncover some surprising new tricks that could...

The Atlantic blue crab, Callinectes sapidus, long prized as a savory meal at a summer party or seafood restaurant, is a multi-million dollar source of income for those who harvest, process and market the crustacean along the U.S. Atlantic and Gulf coasts. Unfortunately, the blue crab population has been declining in recent years under the assault of viruses, bacteria and man-made contaminants. The signs of the attack often are subtle, so researchers from the National Institute of Standards...

Sally Hall, a PhD student at the University of Southampton's School of Ocean and Earth Science (SOES) at the National Oceanography Centre, Southampton (NOCS) has formally described four new species of king crab, all from the deep sea. Hall discovered the new species in the Smithsonian Collections of the National Museum of Natural History in Washington. Explaining the significance of the find, she said: "King crabs include some of the largest crustaceans currently inhabiting Earth and are...

Male Fiddler Crabs will quite happily protect a female neighbor, but do so partly in exchange for sex, according to a new study from The Australian National University. The study by Richard Milner, Professor Michael Jennions and team leader Dr Patricia Backwell of the Research School of Biology at ANU looked at how female fiddler crabs "“ without the large claw that the males are armed with "“ go about protecting their territories. The results of the study are published in Biology...

Crab Spiders, Thomisidae
2014-06-19 08:13:57

Thomisidae is a family that holds around two thousand species of crab spiders that can be found throughout the world. Although the name crab spider has been used to refer to a large number of species, it is most often used to refer to members of this family, especially the flower crab spider. Many members of this family have flat bodies that resemble those of crabs and others hold their two front legs in positions that crabs are known for or move in sideways motions as crabs do. Although...

Crab-eating Raccoon, Procyon cancrivorus
2012-07-20 08:42:55

The crab-eating raccoon (Procyon cancrivorus) is native to South and Central America. Its range includes Trinidad and Tobago, Costa Rica, and extends to the northern areas of Uruguay and Argentina. It prefers a habitat with abundant water resources. Although the name implies that this raccoon’s diet consists of only crabs, it also consumes other crustaceans, like lobster, as well as fruits, amphibians, and turtle eggs. The crab-eating raccoon is similar in appearance to the common...

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
