Fish

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.​

An intriguing new study is offering insights into the origins of sleep, for the first time discovering zebrafish brains shift through several brain states while sleeping, which researchers suggest could be analogous to human slow-wave, and REM sleep.

A new study has developed a novel method to tame one of the world’s most potent toxins, tetrodotoxin, commonly found in the pufferfish. The research demonstrates a way to control the spread of the toxin and harness it into a local anesthetic that can numb targeted regions for up to three days.

The lamprey is not something you’d normally want anywhere near your brain. But now, researchers have used molecules taken from the freaky fish’s immune system to deliver drugs inside the body – and even managed to sneak them into the brain.
