Antarctic King Crabs May Actually Be Native
2013-07-05 05:58:25

Brett Smith for redOrbit.com - Your Universe Online Citing the recent discovery of a major colony of King crabs near Antarctica, some global warming alarmists theorize that rising temperatures have allowed the crabs to claim territory that was previously uninhabitable. According to a new review of crab records published in the journal PLOS ONE, the crabs are not newly established settlers; they've been there all along. The so-called "invasion hypothesis is based on a geographically...

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...

Odor Perception In Terrestrial Hermit Crabs Increased By Humidity

Olfaction in land crabs is still in an early transitional stage between life in water and on land Max Planck scientists have found out that the olfactory system in hermit crabs is still underdeveloped in comparison to that of vinegar flies. While flies have a very sensitive sense of smell and are able to identify various odor molecules in the air, crabs recognize only a few odors, such as the smell of organic acids, amines, aldehydes, or seawater. Humidity significantly enhanced electrical...

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...

King Crabs Invading Antarctica
2011-09-07 07:43:05

  Global warming is the most likely cause of a growing number of king crabs that have been marching along the sea floor toward West Antarctica, according to a report by biologists on Wednesday. The intruder, 'Neolithodes yaldwyni Ahyong and Dawson', a bright-red deep-sea predator that had previously been spotted only in the Ross Sea, on the other side of West Antarctica, is now living and reproducing in abundance on the western edge of the icy continent. Writing in the journal...

University of Florida researchers have described a new species of land crab that documents the first crab extinction during the human era. The loss of the crab likely greatly impacted the ecology of the Hawaiian Islands, as land crabs are major predators, control litter decomposition and help in nutrient cycling and seed dispersal. Their disappearance was caused by the arrival of humans to the islands and resulted in large-scale changes in the state's ecosystem. Researchers said the full...

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...

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...

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...

Two thirds of all different species of freshwater crabs are at risk of becoming extinct, says a new survey.That means that freshwater crabs are some of the most endangered of all groups of animals reviewed thus far. This research is the first worldwide evaluation of the extinction danger of any collection of freshwater invertebrates.Crab species in Southeast Asia are the most vulnerable, mainly due to habitat devastation and pollution.Scientists from the Zoological Society of London and...

Profilicollis
2014-01-05 00:00:00

Profilicollis is a genus of acanthocephalan parasites that are found in crustaceans and shorebirds. Profilicollis parasites use decapod crustaceans as intermediate hosts and species of shorebirds as definitive hosts. The parasite first develops in mole crabs of North and South America. After it infects a mole crab, it becomes dormant until the crab is eaten by a suitable bird, such as a Surf scoter or Herring Gull. Once the parasite has passed through the stomach of the bird, it develops...

The Ruggie (Coenobita rugosus), is a species of land hermit crab native to Australia and the east African coast to the southwest Pacific. The Ruggie has four walking legs, a small pincer, a large pincer, and antennae. When threatened it is able to make a 'chirping' sound by rubbing its large pincer against its shell as a way to deter predators. They vary in color depending on nutritional intake and common colors include green, brown and tan; but black, white, pink, and blue have also been...

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

The Ecuadorian Hermit Crab (Coenobita compressus), also known as the Pacific hermit crab is a species of land hermit crab commonly sold in the United States as a pet, along with the Caribbean hermit crab (Coenobita clypeatus). It is a member of the phylum Arthropoda and the class Malacostraca. Native to Ecuador and Chile, these hermit crabs live on the Pacific seashore around the tidal pools and high-tide zone. Their bodies have adapted to this seashore existence and are able to metabolize...

The Strawberry Land Hermit Crab (Coenobita perlatus), is a species of terrestrial hermit crab. They are native to the Indo-Pacific region, specifically Madagascar, Japan, and Australia and in other areas around the Red Sea and the Pacific. However, they have spread to other Atlantic regions because humans have brought them there. Still, they have a harder time surviving on Cape Cod (Massachusetts) than they do in Kapiti Island (a small island off the coast of Paraparaumu, New Zealand)....
