According to Australian scientists, antibodies found in shark blood could potentially be used to fight cancer. Sharks have antibodies - molecules that fight disease - that are exceptionally adaptable, and tough. Researchers believe they can harness these attributes and use them to slow the spread of cancer. They hope the idea can lead to a new line of drug treatments. The team of researchers found that shark antibodies are capable of withstanding very acidic or alkaline conditions, and are...

By Frank Urquhart A STAGGERING five miles below the surface of the Pacific Ocean, scientists had been hoping, at best, to film a solitary fish able to exist in the deepest reaches of the world's seas. And they assumed anything they succeeded in capturing on film would almost certainly be a "monster" - a weird and ugly specimen similar to the shrivelled samples of deep-sea species preserved in the world's marine research institutes. But a team of marine biologists, led by scientists at...

The Atlantic bluefin tuna is the largest and most sought-after of all tunas, weighing as much as 1,400 pounds and capable of fetching as much as $50,000 or more in Asian markets where its meat is a prized commodity, one big reason why its numbers have declined precipitously since the 1970s. New research findings reported in Science have critical implications for how bluefin tuna are managed on both sides of the Atlantic Ocean. A team of international researchers led by Dr. Jay Rooker of Texas...

In an attempt to help conservation of marine animals and aid in climate change monitoring, scientists using DNA have catalogued and described 100 new species of sharks and rays in Australian waters. More than 90 of the newly named species were identified by scientists in a 1994 book "Sharks and Rays of Australia" but remained scientifically undescribed. One rare species of carpet shark catalogued was found in the belly of another shark. A revised 2009 edition of the book by Australia's peak...

Conservationists agree that major changes to rules on shark finning are needed to preserve the health of the world's shark populations. Confusing regulations and poor enforcement mean rule breaking is common, according to campaign group Oceana. Actor and activist Ted Danson said proper management could rescue the species in decline. Over half of ocean-going sharks, and about a third of European species, are threatened with extinction. Danson said the basic problem is it's a fishery that's not...

By Anonymous A state official put it best: A federal report that documents a continued decline in some species of groundfish despite years of regulation was "extremely frustrating." After reducing the number of fishing days, staying out of certain areas and using nets with bigger mesh, the stocks of some species have not rebounded as hoped, leading to what are expected to be even stricter limits next fishing season. For commercial fishermen and the remaining Maine businesses that...

A recent study reports that nearly 40 percent of freshwater fish species in North America are in trouble, doubling since 1989. According to experts, humans have caused the "silent extinctions" through polluting and damming freshwater habitats. In the first large study of freshwater fish in North America in 19 years, a team of researchers from the US, Canada, and Mexico looked at a species restricted to certain geographic areas.  The decline among these "subspecies" groups is even more...

COULD this be a great white shark emerging from the water just off the Welsh coast? The terrifying picture (right) was shot by fisherman David John while on a fishing trip just 100 yards off the popular tourist destination of Caldey Island. Mr John, 40, from nearby Manorbier, said he just happened to be taking pictures of his girlfriend on his mobile phone when what could be one of the sea's most feared predators leaped from the water. And last night, marine experts refused to rule...

By Bina Venkataraman Fishing season has begun in northern waters, not for prize tuna or marlin, but for tropical fish small enough to fit on an angler's fingertip. Luckily, the fishermen here are seeking neither trophies nor dinner. From July to late October, the Gulf Stream carries these young, dime-size reef dwellers from tropical waters near the Florida Keys and the western Bahamas, and abandons them along the coastline of Long Island. In ichthyologists' lingo, they are known as...

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...

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...

This harmless shark is native to the Pacific Ocean off the coast of Indonesia, it is also found in coastal waters from Japan to India. It lives on the ocean floor in shallow areas around coral reefs, hiding during the day and feeding at night. In Taiwan and Madagascar the whitespotted bamboo shark is used for food. Occasionally this species is kept in home aquariums as pets. The young whitespotted bamboo shark will have a black body covered with white and light blue spots and dark vertical...
