Fish

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.

The lionfish is an invasive species that is currently wreaking havoc in the warm waters of the Bahamas, the Caribbean, and the US southwestern Atlantic and Gulf of Mexico coasts. NCSU scientists initiated a study of lionfish genetics to learn more about their origins and how to control them.

​The growing threat of antibiotic-resistant bacteria is seeing scientists get more and more creative in their search for new drugs that might help us maintain the upper hand. Researchers have uncovered what they say is a potential goldmine of antibiotics in the form of fish slime.
