Sea Creature Believed To Be Extinct Rediscovered In New Zealand
2014-06-18 12:57:16

Gerard LeBlond for redorbit.com - Your Universe Online Recently, Dr. Paul Taylor and some colleagues from the Natural History Museum of London found fossilized remains of Protulophila -- small hydroids similar to jellyfish -- on rocks dated to less than a half-million years ago. These creatures were thought to only be present in the Middle East and Europe, becoming extinct four million years ago. However, a recent discovery in New Zealand has revealed the creature may still exist. The...

Scientists Discover Bending Rules For Animal Wing, Fin Tips
2014-02-18 14:58:33

Marine Biological Laboratory A Navy-sponsored project to design a biologically inspired, swimming jellyfish robot has led scientists to the surprising discovery of common bending rules for the tips of wings, fins, flukes, mollusk feet, and other propulsors across a broad range of animal species. The study, led by John H. Costello of Providence College and the Marine Biological Laboratory (MBL) in Woods Hole, where he is a visiting scientist, is published this week in Nature...

Jellyfish Numbers Shifting Climate Patterns

Brett Smith for redOrbit.com - Your Universe Online Every month, 8 to 12 days after each full moon, Waikiki Beach is invaded by large numbers of box jellyfish. After witnessing the phenomenon countless times, Honolulu lifeguard Landy Blair, in conjunction with researchers at the University of Hawaii at Mānoa, started tracking the numbers of jellyfish that invade the beach with each cycle. Over 170 full moons after they began, the team’s published findings in the latest issue of PLOS...

Building Better Robots Based On Natural Jellyfish Movement

Michael Harper for redOrbit.com - Your Universe Online This past spring, researchers with the Virginia Tech College of Engineering unveiled Cyro, a robotic jellyfish roughly the size of a full-grown man. The robot borrowed swimming techniques from actual jellyfish and could one day be used by the military to autonomously survey the waters, map the sea floors and even monitor the changing climate. Understanding the way jellyfish move through the water was only part of the challenge of...

[ Watch the Video: A Battle Between Robot And Jellyfish ] Brett Smith for redOrbit.com - Your Universe Online Besides being a menace to swimmers and surfers in the ocean, jellyfish disrupt fishing nets, clog water intakes, feed on fish eggs and disrupt ecosystems with their massive swarms. A team of engineers from the Korea Advanced Institute of Science and Technology (KAIST) has devised a new robotic system called JEROS that is designed to combat this sea-faring menace by sucking in...

Cyro Jellyfish Robot Swims Autonomously
2013-03-28 18:55:37

[ Watch the Video: Autonomous Robotic Jellyfish ] Lee Rannals for redOrbit.com — Your Universe Online Researchers from Virginia Tech College of Engineering have created an autonomous robotic jellyfish the size and weight of a grown man. Cyro is a larger model of a robotic jellyfish the team unveiled back in 2012 dubbed RoboJelly, which was about the size of a man's hand. The latest robotic ocean dweller is 5-foot-7-inches in length and weighs 170 pounds. "A larger vehicle...

Experts Say Reports Of Increasing Jellyfish Populations Unjustified
2013-01-01 10:47:15

April Flowers for redOrbit.com - Your Universe Online A widely held perception of a global increase in jellyfish has been challenged by a new international study led by the University of Southampton. Jellyfish proliferations, or blooms, have a visible and substantial impact on coastal populations, including clogged nets for fishermen, stinging waters for tourists, and even choked cooling intake pipes for power plants. A perception that the world's oceans are experiencing trending...

New research from the University of California shows how the ability to detect light could have evolved before anything like an eye. As published today (March 5) in the journal BMC Biology, the research is based on the stinging mechanism in the tiny, brainless and eyeless freshwater polyp Hydra magnipapillata. Part of a group of animals called cnidarians that includes sea anemones, corals and jellyfish, a hydra is essentially a mouth surrounded by tentacles armed with stinging cells, or...

Riding the wind and ocean currents, hordes of blue, alien-like creatures descend upon South Florida's shoreline, entangling beach goers in poisonous tentacles and delivering painful stings by the hundreds. Miami, FL (PRWEB) November 17, 2011 Each invader, in fact, isn't an "it" but a "they" â” a colony of organisms that combine to create a single entity, the Portuguese man-of-war. The seafaring wanderer with the neon-blue gas bag and tentacles as long as 30 feet seems...

The polyps of the new gorgonia discovered, Tauroprimnoa austasensis and Digitogorgia kuekenthali, in the region of Austasen, in the Eastern Weddell Sea, and to the south-east of the Falklands and Isla Nueve (in Chilean Patagonia) respectively, are small and elongated. Both species stand out for the number, shape and layout of the scales of calcium carbonate that cover the polyps, and for the type of ramification of the colonies. "The Tauroprimnoa are characterized by being colonies in the...

Fungia scutaria is a species of mushroom coral in the family Fungiidae. It is found in the Indo-Pacific oceanic region. It occurs on upper reef slopes especially where there is considerable water movement. It is typically found on sand beds or coral fragments. It lives as a single individual rather than as a colony and is detached from the seabed. It has an elongated shape and can grow quite large. The polyp can be up to 6.7 inches long and is embedded in a cup-shaped hollow known as a...

Alcyoniidae is a family of leathery corals that occur globally in temperate and tropical seas. These reef dwellers are often found in wave-exposed areas of reef crests, less turbid waters in lagoons, on steep slopes, under overhangs, and at depths of 100 feet and deeper. A colony of leathery coral is stiff, hard, and inflexible. It is composed of tiny polyps projecting from a shared leathery tissue. There are two kinds of polyps seen in Alcyoniidae corals: autozooids have long trunks and...
