African Tiger Fish Eats Bird
2014-01-13 11:30:38

Brett Smith for redOrbit.com - Your Universe Online Stories of the African tiger fish preying on birds in mid-flight have been circulating for years and a research team from South Africa has finally captured evidence of this behavior, according to a new study in the Journal of Fish Biology. “The whole action of jumping and catching the swallow in flight happens so incredibly quickly that after we first saw it, it took all of us a while to really fully comprehend what we had just...

Biofluorescence In Fish
2014-01-09 15:16:51

[ Watch the Video: Strange Lights In The Deep, Dark Ocean? ] Brett Smith for redOrbit.com - Your Universe Online A new study in the journal PLOS ONE has revealed biofluorescence in over 180 fish species and opened the door to the discovery of new fluorescent proteins that could be used in biomedical research. When organisms biofluoresce, they absorb light, convert it, and send it back out as a different color. "We've long known about biofluorescence underwater in organisms like...

Great Whites Older Than Thought

[ Watch the Video: Great White Sharks Live Long And Prosper ] Brett Smith for redOrbit.com - Your Universe Online Great white sharks have always been considered one of the longer living fish, but a new study in the journal PLOS ONE has found that they actually live much longer than previously believed. Using a radiocarbon analysis, study researchers from the Woods Hole Oceanographic Institution (WHOI) and National Oceanic and Atmospheric Administration (NOAA) discovered that male...

Coral Reefs Tracking Tiger Sharks
2014-01-09 09:02:01

Brett Smith for redOrbit.com - Your Universe Online A new study tracking the migratory patterns of tiger sharks in the waters near Australia revealed just how important coral reefs are to the survival of this feisty predator. The study was published in the journal PLOS ONE on Wednesday and showed that coastal marine parks provide only temporary protection for the sharks. "In this study we looked at migratory movements and fidelity to specific reefs for tiger sharks tagged in New...

Elephant Shark DNA Decoded
2014-01-08 15:35:28

Ranjini Raghunath for redOrbit.com - Your Universe Online An international team of scientists has deciphered the genetic blueprint of the elephant shark - the oldest living animal in the cartilaginous fish family and the first to have its DNA decoded. Among fish, cartilaginous fish such as sharks and rays stand out because their skeleton is not made of bones. Their body is supported instead by cartilage, a flexible tissue that resembles muscle. Analysis of the elephant shark’s DNA...

Ancient Shark Spawned Like Salmon
2014-01-07 15:16:19

[ Watch the Video: Evidence Of Ancient Shark Migration In Reverse ] Brett Smith for redOrbit.com - Your Universe Online A new study published on Tuesday in the Journal of Vertebrate Paleontology has found that a certain species of ancient shark behaved like salmon in reverse – swimming from freshwater into the ocean for spawning. The study of the long-snouted Bandringa provides the earliest known evidence of shark migration – which took place 310 million years ago in a region now...

Ocean Currents Drive Eel Population Changes: Study
2013-12-29 08:18:16

Ranjini Raghunath for redOrbit.com - Your Universe Online Fluctuations in the European eel population – a long-time holiday delicacy – may be linked to changing ocean currents in the Atlantic, according to new research published in the journal Current Biology. The European eel gives birth in the Sargasso Sea and the larvae drift towards the European coast 2700 miles away. There, in fresh water and along the coast, they grow and mature into adults, before returning to the Sargasso...

New study has implications for conservation Bonefish, also called gray ghosts, are among the most elusive and highly prized fishes sought by recreational anglers in the Florida Keys, Bahamas and similar tropical habitats around the world. Bonefish support a fishery worth hundreds of millions of dollars annually, but this fishery is threatened in many areas by habitat loss and degradation, and by overfishing. Scientists are scrambling to identify and protect critical habitats and identify...

Sharks Humans Proteins In Common
2013-12-06 08:32:39

redOrbit Staff & Wire Reports - Your Universe Online Many shark proteins, involved in a number of different functions, match those of humans more closely than they do those of zebrafish. Cornell University researchers reported  this resemblance on Thursday, after an extensive investigation into the genetic code of endangered great white sharks. Despite a longstanding fascination with great whites, whose body design has been so effective that it has barely changed since the time of...

Shark Attack From Behind
2013-12-05 15:58:13

Brett Smith for redOrbit.com - Your Universe Online As if the razor-sharp teeth, powerful jaws and lightning-quick speed weren’t enough, a pair of marine biologists have now found that sharks prefer to attack from behind, according to a new study in the journal Animal Cognition. Previous research has shown that many predators, including sharks, attempt to perceive the body shape, size and movement of their potential prey. Marine biologists have also found that sharks prefer to...

Prowfish
2014-05-30 12:05:29

The prowfish (Zaprora silenus) is a subtropical species of a perch-like fish found in the northern Pacific Ocean. The range of the prowfish is from the Aleutian Islands, Alaska to Kamchatka, Russia, from Navarin Canyon in the Bering Sea to Hokkaido, Japan and Monterey, California. The preferred habitat of the prowish is rocky bottom at a maximum of 2,200 feet in depth where they spend most of their adult life. Prowfish can grow to a length of 40 inches or more having an elongated body that...

Bluefish, Pomatomus saltatrix

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...

Ichthyology
2013-10-02 13:31:45

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...

Little tunny, Euthynnus alletteratus
2013-03-28 14:07:39

The little tunny is found widespread in temperate and tropical waters of the Atlantic Ocean, Black Sea and Mediterranean Sea. It is the most common tuna and is highly migratory, with a range from Cape Cod, Massachusetts to Brazil in the Western Atlantic. In the Eastern Atlantic it is found from Skagerrak to South Africa. The little tunny will form schools close to the shoreline, around inlets, and sandbars that can cover up to two miles. This fish prefers warm water and will migrate south in...

Image Credit: WA Djatmiko/Wikipedia (CC BY-SA 3.0, 2.5, 2.0 and 1.0) The African sharptooth catfish is native throughout Africa, and the Middle East, and in the 1980’s it was introduced all over the world. This catfish lives on muddy bottoms in freshwater lakes, rivers, swamps, man-made habitats, and occasionally found in urban sewage systems. This species is able to crawl across dry ground to another body of water when one pool dries up. It is also able to survive for long periods of...
