Extinct Arthropod Had Big Claws Spider Brain
2013-10-16 15:15:35

Brett Smith for redOrbit.com - Your Universe Online While finding an intact fossil of any kind can be an exciting discovery, an international team of paleontologists recently discovered the earliest known complete nervous system in the fossil of a never-before described creature that crawled or swam in the ocean some 520 million years ago, according to a report in the journal Nature. The researchers said the fossil belongs to an extinct group of marine arthropods known as megacheirans,...

Coral Decline Affects Crustacean Biodiversity
2013-09-23 15:48:53

Brett Smith for redOrbit.com - Your Universe Online With many scientists expecting climate change to have a devastating effect on the world’s coral reefs over the coming century, new research from the University of Florida indicates that crustacean populations living near rapidly declining reef habitats could be at risk. Appearing in the November issue of the journal Geology, the new study is based on an analysis of the fossil record surrounding decapod crustaceans, a group that...

Switching To A Power Stroke Helps A Tiny Marine Crustacean To Survive
2013-04-02 14:29:14

University of Texas at Austin [ Watch the Video Copepod Nauplius Swimming at 10 Degrees C ] Olympic swimmers aren't the only ones who change their strokes to escape competitors. To escape from the jaws and claws of predators in cold, viscous water, marine copepods switch from a wave-like swimming stroke to big power strokes, a behavior that has now been revealed thanks to 3-D high-speed digital holography. Copepods are tiny crustaceans found in nearly every aquatic environment on...

Astronauts Return With New Life
2012-11-23 12:48:43

ESA It is not every day that astronauts can claim to return to Earth with a new species of life. But when the astronauts on ESA´s CAVES underground training course returned to the surface they were carrying a special type of woodlouse. CAVES training sends astronauts from all the International Space Station partner nations underground for a week to learn about working in multi-cultural teams under extreme conditions. During their six-night stay in caves in Sardinia, Italy, their...

Evolution Of Complex Brains
2012-10-11 04:52:39

April Flowers for redOrbit.com - Your Universe Online Anatomically complex brains evolved earlier than previously thought and have changed little over the course of time, according to a new study by University of Arizona neurobiologist Nicholas Strausfeld. The specimen described in the study, which will be published in the October 11 issue of Nature, is the earliest known fossil to show a brain. The three inch long fossil was discovered embedded in mudstones deposited during the...

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...

Researchers Find King-sized Crustacean In Deep Pacific Trench
2012-02-03 08:48:10

During an expedition to the Kermadec Trench north of New Zealand in the Pacific Ocean researchers discovered a ℠supergiant´ amphipod measuring 10 times the size of typical amphipods. Typically deep sea amphipods are about an inch long (2-3 centimeters) with the exception of the ℠giant´ amphipod found in Antarctica which can be up to 4 inches long (10 centimeters). But the latest discovery, in the world´s deepest ocean at depths of 23,000 feet, measures an...

Researcher narrows down spread of first lobster virus From the Florida Keys to Cuba to the Bahamas and Belize, tourists and locals enjoy the taste of the Caribbean spiny lobster. Family operations and commercial fisheries alike depend on its popularity, so the lobster is important to many local economies. But this crustacean is threatened by a virus called Panulirus argus virus 1 (PaV1). "We know that it can spread between lobsters. They can eat infected tissue and contract it that...

There are many different kinds of crustaceans, ranging from the shellfish Swedish people eat at traditional crayfish parties every August to tiny relatives found in their millions in both freshwater and saltwater. One of the latter, Daphnia pulex, is the first crustacean to have its genome sequenced. A researcher from the University of Gothenburg has made a surprising discovery. The sequencing has been done in an international research network known as the Daphnia Genomics Consortium. The...

By Greg Hand, University of Cincinnati Fossilized "snapshots" provide University of Cincinnati paleontologist Carlton E. Brett and colleagues with new insights into the behavior of ancient marine creatures. Brett will present this research March 20 at the regional meeting of the Geological Society of America in Pittsburgh. Few specimens inspire greater thrills among fossil collectors than a complete trilobite. These ancient arthropods "“ relatives of lobsters, spiders and insects...

The Ghost Shrimp, Pestarella tyrrhena is a species of thalassinidean crustacean that dwells in shallow, sandy tunnels of the ocean floor in the Mediterranean Sea and northern Atlantic Ocean. Initially, the crustacean derived its name from the Tyrrhenian Sea where it inhabited. The crustacean was called formerly Callianassa tyrrhena, but current common terminology for the species is Ghost Shrimp or Mud Shrimp. Fishermen in the Mediterranean have used it as bait for at least 200 years...
