Fish

The annual Ocean Art Underwater Photo competition, now in its eighth year, is a chance to get up close and personal with our marine cousins so many times removed. Here are all this year's winners and runners up in a spectacular photo gallery.

A Phase 3 clinical trial into the efficacy of a fish-oil-derived drug called Epanova has been discontinued. The trial was designed to establish the use of the drug, a formulation of two omega-3 fatty acids, as an adjunct to statins for heart disease.

The FDA has expanded its approval of a fish oil-derived drug designed to reduce risk of cardiovascular events in adults with elevated triglyceride levels. The drug was initially approved in 2012, but limited to a highly specific sub-set of patients.

An international team of researchers suggests that a wide variety of marine species could be used for monitoring the world's oceans. Using electronic tags, exploiting their natural behavior could fill gaps in our knowledge of the seas.

We recently heard how scientists from the University of Washington had developed a suction cup inspired by the clingfish. Well, researchers at UC San Diego have taken a different approach to create one of their own, and they've even used it on an underwater robot.

Scientists have developed a clingfish-inspired suction cup, that outperforms the actual fish itself.

American scientists have created a "Tunabot," that they claim can match the swimming speed of an actual tuna.

Scientists have copied the porcupinefish's spines to create a water-repellent material that's more robust than previous efforts.

Scientists have found that the electric eel comes in three species rather than one and that one of these is a real shocker.

Inspired by remora fish, researchers at NJIT have designed a new suction cup that’s far more adhesive than the real thing.

Viewers of the various "extreme angling" TV shows have likely already heard that it's getting more difficult to find big fish in the world's lakes and rivers. A new international study, however, now confirms that there has recently been a drastic decline in populations of large freshwater animals.

​​Fans of a still-surviving megalodon, rejoice – a new species of deep-ocean shark has been identified. At just 5.5 inches long (about 144 mm), however, the American Pocket Shark is a bit smaller than the prehistoric super-predator.​
