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...

Sharks Go Home To Give Birth
2013-12-05 14:07:20

[ Watch The Video: Lemon Shark Giving Birth ] Lee Rannals for redOrbit.com - Your Universe Online New findings published in the journal Molecular Ecology shows that sharks head back to their origins to give birth. Salmon and sea turtles are known to head back to their birthplace in order to lay eggs, but this is the first time that scientists have confirmed that sharks do the same. These findings could have a big impact on local shark conservation efforts. Researchers conducted a...

A Fish Out Of Water Relies On Camouflage To Escape Predation
2013-12-02 13:53:04

[ Watch the Video: Land-Dwelling Fish ] Brett Smith for redOrbit.com - Your Universe Online A leaping, legless, land-loving fish called the Pacific leaping blenny isn’t just one of the odder creatures found on Earth – it’s also emblematic of life’s transition from life in water to life on land. A new study published in the journal Animal Behaviour has found these strange fish-out-of-water depend on camouflage to escape would-be predators. "This terrestrial fish spends all...

Unexpected Features Found Via Great White Shark Genome Study
2013-11-20 07:13:08

[ Watch the Video: Genome Of The Great White Shark ] April Flowers for redOrbit.com - Your Universe Online Made famous by the horror movie "Jaws," the great white shark is an apex predator that has become an iconic species by capturing an extraordinary amount of public fascination. What makes this particular shark so distinctive? A new study, published in BMC Genomics, addresses this question by exploring the genetic makeup of this remarkable animal. A team of scientists from Nova...

No other modern animal may command both our fears and fascination as much as the great white shark – but The Maritime Aquarium’s new IMAX film suggests, instead, that these incredible predators mainly need our help and respect. “Great White Shark” unravels the mystery of the creature we love to fear in telling the true story of its role atop the oceanic food chain. Norwalk, CT (PRWEB) November 11, 2013 We're not going to need a bigger screen. The six-story screen of The...

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...

African Sharptooth Catfish, Clarias gariepinus

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...
