Thresher Sharks Take Down Prey With Whip-Like Tail
2013-07-11 10:44:42

Brett Smith for redOrbit.com - Your Universe Online Named after its long whip-like tail, the thresher shark uses its eponymous feature not only to swim, but also to strike at prey. An international team of marine biologists has captured and analyzed rare videos depicting the sharks' unusual hunting style, according to a report in the journal PLoS ONE. Shot in the tropical waters off the coast of the Philippines, the videos show pelagic thresher sharks accelerating toward schools of...

Coral Reef Protection From Cloud Seeding
2013-07-11 04:51:24

April Flowers for redOrbit.com - Your Universe Online New research from the University of Leeds reveals threatened coral reefs could be protected from bleaching by warming oceans. The study proposes a targeted version of the geoengineering technique known as Marine Cloud Brightening (MCB) - seeding the clouds to cool sea surface temperatures - could give coral a fifty year "breathing space" to recover from acidification and warming. "Coral bleaching over the last few decades has been...

Ocean Acidification Has Transformed Delicate Ecosystem
2013-07-09 15:43:58

Brett Smith for redOrbit.com - Your Universe Online While many studies have focused on how ocean acidification may impact various individual species, an international team of researchers has just published a study on how an entire ecosystem can be affected by a more acidic ocean. As one of the consequences of climate change, ocean acidification is expected to significantly increase if carbon emissions continue at current rates. According to the study, which was published in...

Fish Species That Thrive In Bay Bottoms Are Being Impacted By Dead Zones
2013-07-09 07:35:36

April Flowers for redOrbit.com - Your Universe Online Scientists at the Virginia Institute of Marine Science (VIMS) have completed a 10-year study, providing the first quantitative evidence on a bay-wide scale that the distribution and abundance of "demersal" fishes -- fish species that live and feed near the Bay bottom -- are being impacted by low-oxygen "dead zones." Species affected by these dead zones, such as the Atlantic croaker, white perch, spot, striped bass and summer...

Juvenile Reef Fish Use The Sun Compass To Guide Them To Safety
2013-07-08 09:32:57

Brett Smith for redOrbit.com - Your Universe Online When reef fish hatch from their eggs, they are immediately swept out to sea -- sometimes miles from the safety of their coral homes. Once they are able to swim, these fish must begin the arduous trek back or risk getting devoured in the open waters. The tiny fishes' uncanny ability to locate their home reef has captivated scientists and a new study in the journal PLoS ONE revealed these fish use the sun's position in the sky to...

Sea Lettuce Invades Chinese Beach
2013-07-06 05:51:46

redOrbit Staff & Wire Reports - Your Universe Online It may be called the Yellow Sea, but the northern part of the East China Sea has turned green due to the largest algal bloom in the history of the Asian nation, various media outlets are reporting. According to AFP news agency reports, the State Oceanic Administration is reporting that the algae, which is known as Enteromorpha prolifera, started appearing about one week ago, and among the places affected are a public beach in...

Global Warming Will Not Affect Jumping Snails' Ability To Leap
2013-07-05 08:52:24

Society for Experimental Biology Snails in the Great Barrier Reef literally jump for their life to avoid predators. But will they be able to maintain these life-saving jumps, with rising sea temperatures? A new study, to be presented at the Society for Experimental Biology meeting in Valencia on July 5, shows that the snails will indeed be able to keep on jumping, even at temperatures which will kill fish. The Great Barrier Reef humpbacked conch snail jumps when it senses the odor of...

Our Immune Defenses Originated In Corals 070113
2013-07-01 12:01:26

Brett Smith for redOrbit.com - Your Universe Online Many biological processes have their roots in the very earliest stages of life's evolutionary tree, and new research in the journal BMC Genomics indicates that part of our immune system comes from coral-like ancestors. According to the study, molecular biologists at the ARC Centre of Excellence for Coral Reef Studies (CoECRS) have found genes in Acropora, or staghorn, corals which are responsible for a quick, strong immune response to...

Scuba Fishing Ban To Preserve Hawaii's Vulnerable Species
2013-07-01 10:57:23

Brett Smith for redOrbit.com - Your Universe Online A contentious debate is stirring in the Aloha State between fishermen and those looking to preserve species living in the regions' coral reefs. Hawaii's Board of Land and Natural Resources recently voted to ban spear fishing with scuba gear off the west coast of the state's main island as well as the collection of 40 different species for aquariums. The regulations were approved 4-2 after six hours of hearings. According to...

If Carbon Emissions Aren't Reduced Now, Coral Reefs Will Die
2013-06-28 15:24:29

Lee Rannals for redOrbit.com - Your Universe Online A new study found that in order to prevent coral reefs from dying off, nations need to work hard to drop carbon dioxide emission levels. Researchers wrote in the journal Environmental Research Letters that all existing coral reefs will die from inhospitable ocean chemistry conditions by the end of the century if civilization continues on its current path. Coral reefs are havens for marine biodiversity and underpin the economies of...

Crown Of Thorns Starfish, Acanthaster planci
2013-11-11 10:54:41

The crown-of-thorns starfish (Acanthaster planci) is a species of starfish that is classified within the Acanthasteridae family. This species has a large range that extends from the Red Sea to the African coasts in the east and from the Indian Ocean to the western coasts of Central America. It prefers a habitat in coral reefs, which can be harmed if population numbers are too high. Damage occurs when filamentous algae covers bare skeletons of coral and the starfish move in to feed, stripping...

Bluefish, Pomatomus saltatrix
2013-10-22 10:54:52

The Bluefish (Pomatomus saltatrix) is the only living species of the family Pomatomidae. It is a marine pelagic fish that can be found around the world in temperate and subtropical waters, except for the northern Pacific Ocean. Bluefish are known as tailor in Australia, shad on the east coast of South Africa, and elf on the west coast. Other common names regarding this fish are blue, chopper, and anchoa. It is a good eating and game fish. The bluefish is moderately proportioned with a...

Lampert's Sea Cucumber, Synaptula lamperti
2013-04-30 15:18:06

Synaptula lamperti is a species of sea cucumber that can be found in the waters of the Indo-Pacific. Its range includes the coastal waters of Papua New Guinea, the Philippines, Indonesia, and Micronesia. It does not have the tube feet, which are common to other species of sea cucumber, instead moving around by using a small grouping of pinnate feeding tentacles, which are always moving. It can also move by using the small, hook-like bones found along its body, attaching itself to the sea...

Mudflats
2013-04-19 21:07:34

Mudflats, or otherwise known as tidal flats, are coastal wetlands that form when mud is left behind by tides or rivers. They’re found in sheltered regions such as bayous, lagoons, estuaries, and bays. Mudflats might be seen geologically as exposed layers of bay mud, a result from the deposition of estuarine silts, marine animal detritus, and clays. The majority of the sediment in a mudflat is within the intertidal zone, therefore the flat is submerged and exposed about twice per day. In...

Kelp Forest
2013-04-19 19:29:03

Kelp forests are areas that are underwater with a high density of kelp. They’re recognized as one of the most dynamic and productive ecosystems on Earth. Smaller regions of anchored kelp are known as kelp beds. Kelp forests can be found worldwide throughout polar and temperate coastal oceans. In the year 2007, kelp forests were discovered in tropical waters near Ecuador as well. While they are physically formed by brown macroalgae of the order Laminariales, kelp forests offer a unique...
