New Species Of Sea Bass Identified Based On Larval, Adult Specimen
2014-05-14 13:14:48

Brett Smith for redOrbit.com - Your Universe Online Thanks to a lot of hard work and a little luck – two scientists from the National Museum of Natural History at the Smithsonian Institution have identified a mysterious larval fish and the same fish in its adult stage as a new species of sea bass. Most fish that live in the ocean have a pelagic larval stage that floats inside the surface or near-surface currents, an ecosystem very distinct from the one they occupy as adults. Two...

Fish Larvae Use Small Of Corals To Get Home

[ Watch The Video: o-DISC Deployed Off One Reef Island ] Lee Rannals for redOrbit.com - Your Universe Online Scientists writing in the journal PLOS ONE say that if fish larvae were lost, they could just sniff their way back home. The study establishes that reef fish larvae can smell the presence of coral reefs from as far away as several miles offshore. The larvae are then able to use this scent to help guide themselves back home. The researchers were aiming to study the response of...

New Method Developed For Estimating Fish Movements Underwater
2013-08-23 11:24:41

University of Hawaiʻi at Mānoa How do you track a fish? There’s no “Google Maps” for finding fish. The radio signals that are the backbone of traditional GPS cannot pass through seawater. But sound travels remarkably well, so scientists often use acoustic telemetry to estimate an individual fish’s location. That means attaching an acoustic transmitter to a fish and then using a network of stationary underwater listening stations to monitor for the short clicking sounds that...

Fish Species Losing Homes As Sea Anemones Suffer From Bleaching
2013-08-20 10:13:39

Brett Smith for redOrbit.com - Your Universe Online Marine biologists have been warning recently about the dangers of coral bleaching and new research from a team of international scientists indicates sea anemones are also susceptible to the color-sapping phenomenon that is thought to result from death of sea creatures’ symbiotic algae. In addition to being suspected of causing an increase in sea anemone mortality, bleaching also affects clownfish and 27 other fish species that depend...

Small prey fish can grow a bigger ‘eye’ on their rear fins as a way of distracting predators and dramatically boosting their chances of survival, new scientific research has found. Researchers from Australia’s ARC Centre of Excellence for Coral Reef Studies (CoECRS) have made a world-first discovery that, when constantly threatened with being eaten, small damsel fish not only grow a larger false ‘eye spot’ near their tail – but also reduce the size of their real eyes. The...

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...

Tiny coral reef wrasses can swim as fast as some of the swiftest fish in the ocean — but using only half as much energy to do so, Australian scientists working on the Great Barrier Reef have found. By flapping their fins in a figure-eight pattern, bluelined wrasses can travel at high speeds while using 40 per cent less energy than tunas of the same size. “For a long time, people thought the best high-speed swimmers were the fishes cruising in open waters, like mackerel and...
