Fishes account for over half of vertebrate species, but while groups such as mammals, birds and reptiles have been fairly well understood by scientists for decades, knowledge about relationships among many types of fishes was essentially unknown — until now. A team of scientists led by Richard Broughton, associate professor of biology at the University of Oklahoma, published two studies that dramatically increase understanding of fish evolution and their relationships. They...

Effects Of Changing Ocean pH May Result In Increase In The Hearing Sensitivity Of Fish
2013-04-19 14:26:57

University of Miami Rosenstiel School of Marine & Atmospheric Science Ocean acidification, which occurs as CO2 is absorbed by the world's oceans, is known to negatively impact a wide variety of marine animals ranging from massive corals to microscopic plankton. However, there is much less information about how fish may be impacted by acidification, should carbon emissions continue to rise as a result of human activities. In a new study published in the Proceedings of the National...

Scientists Say More Large Ocean Wilderness Parks Needed
2013-04-15 08:43:45

ARC Centre of Excellence for Coral Reef Studies Leading international marine scientists have called for the protection of more, large marine wilderness areas in a bid to shield the world´s dwindling stocks of fish from destruction. Working in the world´s largest unfished marine reserve, the remote Chagos Archipelago in the central Indian Ocean, scientists from Australia and the US have shown there is a dramatic difference in the numbers, size and variety of fish compared with...

Research Now Allows Fishermen To Harvest Lucrative Shellfish On Georges Bank
2013-04-11 09:51:25

Woods Hole Oceanographic Institution Combined research efforts by scientists involved in the Gulf of Maine Toxicity (GOMTOX) project, funded by NOAA´s Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) program, and administered by the National Centers for Coastal Ocean Science (NCCOS), have led to enhanced understanding of toxic algal blooms on Georges Bank. This new information, coupled with an at-sea and dockside testing protocol developed through collaboration between GOMTOX...

Sea Urchins Prepared For Future Climate Change
2013-04-10 05:47:43

[ Watch the Video: Ocean Babies on Acid - The Time Machine ] Lee Rannals for redOrbit.com - Your Universe Online Scientists have uncovered some surprising abilities in sea urchins living along the coast of California and Oregon. A group from Stanford discovered that some purple sea urchins have the ability to rapidly evolve in acidic ocean water, which is a skill that could come in handy as climate change increases. This ability allows urchins to have healthy growth in water with...

Ocellated Ice Fish In Japanese Aquarium Has Clear Blood
2013-04-07 07:03:28

redOrbit Staff & Wire Reports - Your Universe Online An unusual species of fish caught in the Antarctic Ocean two years ago has no scales and completely transparent blood, according to experts at Japan´s Tokyo Sea Life Park. The aquarium is the only place in the world that currently has the unusual creature, which is known as the Ocellated Ice Fish, in captivity. Researchers there say that the fish has clear blood because of it lacks hemoglobin — the protein which gives...

Key Role In Marine Ecosystem Health Played By Tiny Grazers
2013-04-03 10:55:32

USGS Tiny sea creatures no bigger than a thumbtack are being credited for playing a key role in helping provide healthy habitats for many kinds of seafood, according to a new study by the Virginia Institute of Marine Science and U.S. Geological Survey. The little crustacean “grazers,” some resembling tiny shrimp, are critical in protecting seagrasses from overgrowth by algae, helping keep these aquatic havens healthy for native and economically important species. ...

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...

Algae Blooms Could Be A Sign Of Things To Come
2013-04-02 04:43:11

redOrbit Staff & Wire Reports - Your Universe Online Instead of being an isolated occurrence, a record-breaking 2011 algae bloom in Lake Erie could be a harbinger of things to come, researchers report in this week's online early edition of the journal Proceedings of the National Academy of Sciences (PNAS). The hazardous algae bloom — the largest in the recorded history of Lake Erie — was likely caused by long-term changes to farming practices in combination with weather...

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...
