redOrbit Staff & Wire Reports - Your Universe Online A newly-identified genetic association with facial asymmetry in ancient cavefish could shed new light into mysteries surrounding conditions such as cleft palate or hemifacial microsomia in humans, according to research appearing in a recent edition of the peer-reviewed journal Genetics. Joshua Gross, an assistant professor in the University of Cincinnati’s Department of Biological Sciences, and his colleagues compared the...

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...

Perceived risk of predation increased acceptance of immigrants into group Cichlid fish are more likely to accept immigrants into their group when they are under threat from predators and need reinforcements, new research shows. The researcher suggests that there are parallels between cooperatively breeding fish's and humans' regulation of immigrants. The research was published today, 6 February 2013, in the journal Proceedings of the Royal Society B. The Princess of Lake Tanganyika...

Ocean Warming Is Shrinking Fish Size
2012-10-01 09:33:57

Brett Smith for redOrbit.com - Your Universe Online New research by a team of North American scientists indicates that warmer water may cause shrinkage in average fish size and populations of fish stocks. "We were surprised to see such a large decrease in fish size," said William Cheung, a professor at the University of British Columbia and lead author of a report on the team´s research that was published in the journal Nature Climate Change. "Marine fish are generally known to...

On land, being small and lurking at the bottom of the food chain is a far better strategy for species survival than being big, fierce and perched on top, at least when humans are after you "“ just ask the mice and grizzly bears. But talk to sharks and anchovies and they'll tell you a different story, according to a new study of fisheries collapses led by Stanford researchers. Analyzing over 200 scientific assessments of fisheries around the globe, the team found that populations of...

Whether a fish likes to hunt down its food or wait for dinner to arrive is linked to the composition of its brain, a University of Guelph researcher has revealed. Prof. Rob McLaughlin has discovered that foraging behaviour of brook trout is related to the size of a particular region in the fish's brain. "We found that the fish that swim around in the open in search of food have larger telencephalons than the fish that sit along the shoreline and wait for food to swim by in the water column,"...

What are the long-term evolutionary implications of prolonged fishing for the fish that humans and, perhaps more importantly, diverse ecosystems so depend on? For many of the types of fish we buy in stores or order in restaurants, the chance that an individual dies from fishing is several times higher than dying of natural causes. This may seem obvious to most (they had to get to our table somehow), but what may not be apparent is that the relentless pursuit of consumer-friendly fish product...

Using snorkelers and SCUBA divers is not the best way to monitor fish populations, if we want to know the evolutionary effects of overfishing. The fish population in coral reef areas is often assessed by snorkelers or SCUBA divers, but new research shows that these methods may misrepresent the number of fish. A study from the University of Victoria shows that fish avoid the divers and snorkelers who try to count them. Not all types of fish are equally frightened by the divers, and Faculty of...

The same types of fishes are vulnerable today Large size and a fast bite spelled doom for bony fishes during the last mass extinction 65 million years ago, according to a new study to be published March 31, 2009, in the Proceedings of the National Academy of Sciences. Today, those same features characterize large predatory bony fishes, such as tuna and billfishes, that are currently in decline and at risk of extinction themselves, said Matt Friedman, author of the study and a graduate student...

Eating certain fish -- except fried -- lowers the risk of silent strokes that can lead to dementia and stroke, Finnish researchers said. Silent brain infarcts -- only detectable by brain scans and found in about 20 percent of otherwise healthy elderly people -- can lead to dementia and stroke. The study, published in the journal Neurology, found those eating tuna, salmon, mackerel, herring, sardines or anchovies three times or more per week had a nearly 26 percent lower risk of having...

White-spotted Puffer, Arothron Hispidus
2013-01-12 08:14:01

The white-spotted puffer is found around coral reefs, sea grass, tide pools, estuaries, and lagoons. In the South-East Atlantic Ocean, Indo-Pacific Ocean, Red Sea, Japan, Hawaiian Islands, and also off the southern coast of California at a depth of up to 115 feet. The adult is semi-aggressive, territorial, and nocturnal, hiding during the day and feeding at night. When threatened, this fish will puff up to deter predators. The body of this puffer is covered in a poisonous mucus and can be...

The Spotted Trunkfish (Lactophrys bicaudalis) is a species of fish found in reefs throughout the Pacific Ocean and Indian Ocean as well as the south eastern Atlantic Ocean. It gets its name from the black spots it has covered over its yellow/golden body. Like all trunkfish in the Genus Lactophrys, the Spotted Trunkfish secretes a colorless ciguatera toxin from glands on its skin when touched. It is only dangerous if ingested. Predatory fish, as large as nurse sharks, can die as a result...
