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...

Brett Smith for redOrbit.com – Your Universe Online Just like the rapper Drake, ray-finned fish started from the bottom – now they’re here. The vertebrate class of fish, which comprises 99 percent of all fish species, arose from a small, shell-crushing predatory fish called Fouldenia that survived a massive extinction event 359 million years ago, according to a new report in Zoological Journal of the Linnean Society. "This event 359 million years ago is called...

Fish Relatives Surprise Scientists
2013-07-18 04:53:01

Susan Bowen for redOrbit.com - Your Universe Online Scientists have used genetic data to create a comprehensive evolutionary family tree, or phylogeny, for "spiny-rayed fish," a category that encompasses about a third of all living vertebrate species. They were quite surprised to find out just who was related to whom in the fish world. The researchers, who published their findings in the Proceedings of the National Academy of Sciences looked at 10 genes in more than 500 fish species...

Great White Sharks Use Stored Liver Oil As Fuel For Long Trips
2013-07-17 18:58:39

Brett Smith for redOrbit.com - Your Universe Online While not quite as exciting as last week's Sharknado, a report from Stanford University just published in Proceedings of the Royal Society B has revealed new details on how great white sharks can make non-stop voyages that extend 2,500 miles or more. According to the report, the sharks store excess energy after feeding in the form of liver oil, which they can tap into on long trips. "We have a glimpse now of how white sharks come in...

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.

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...

Ichthyology is the study of fish that focuses on many types of fish including cartilaginous fish, jawless fish, and skeletal fish. This branch of zoology can be associated with marine biology and fisheries science, as well as other areas of study. Ichthyologists, those who practice ichthyology, have discovered more than 32,200 species of fish, and it is thought that they discover 250 new species each year. Humans first began to study fish during the Upper Paleolithic Revolution, when humans...
