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...

New Insight Into Evolution Offered From Unusual Anal Fin
2013-04-10 09:31:33

University of Manchester An unusual fossil fish that has fins behind its anus could have implications for human evolution according to a scientist at The University of Manchester. Dr Robert Sansom from the Faculty of Life Sciences identified the paired fins of Euphanerops, a fossil jawless fish that swam in the seas around 370 million years ago. The find makes the fish one of the first vertebrate to develop paired appendages such as fins, legs or arms. However, their positioning is...

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...

Shark Tooth Weapons Lead To Discovery Of Extinct Marine Species
2013-04-04 12:28:23

Brett Smith for redOrbit.com - Your Universe Online Sharks played a key role in the lives of ancient Pacific islanders. Not only were these animals hunted as food, but their teeth were also used to create deadly weapons. Based on an analysis of ancient weapons found on the Gilbert Islands, modern day biologists said they have discovered two locally extinct species of shark that once inhabited the central Pacific. According to Joshua Drew, a biologist at New York's Columbia University...

Sharks Endangered Globally Due To Overfishing

redOrbit Staff & Wire Reports - Your Universe Online Overfishing kills an average of 100 million sharks worldwide each year, according to new research highlighting the dangers faced by many different species of fish as they attempt to avoid possible extinction. According to Dan Stone of National Geographic Magazine, biologists from  Dalhousie University in Canada and colleagues used data obtained from global shark catch reports and nearly 100 past research papers to estimate...

California Great White Sharks May Get Endangered Species Status
2013-02-07 14:59:48

Brett Smith for redOrbit.com - Your Universe Online On Wednesday, California's Fish and Game Commission recommended that the endangered status be given to great white sharks in the waters under their jurisdiction.
