A benzodiazepine seeping into waterways is causing young Atlantic salmon to behave strangely, with fish in the wild migrating more rapidly and taking more risks on their journey from river to ocean. It even seems to be messing up their social lives.

Researchers have found compelling evidence to confirm that a specific pod of clever killer whiles in the Gulf of California has developed an astonishing new skill: hunting enormous whale sharks by attacking their undersides.

Imagine being horribly maimed and the only way to survive was to merge your damaged flesh with another injured human. Scientists have discovered this startling ability in comb jellies, which can fuse together to share a nervous and digestive system.

Last year, it was discovered the bluestreak cleaner wrasse could pass the "mirror test", showing that it can recognize its own face in a mirror. Now researchers have found it can actually size itself up against a potential competitor before a fight.

A pigment molecule in cephalopod skin has had its antioxidant and sun-protection properties harnessed, inspiring the first ultra-protective, skin-restorative and environmentally safe sunscreen of its kind. And it could revolutionize the skincare world.

A daredevil seabird species has learnt to harness the insane power of hurricanes, seeking out storms over the ocean to 'ride' them for their own benefit. It's the first time this behavior has been observed, and now has scientists wondering if it's far more widespread in the avian world.

While you're more likely to win the lottery than become a tasty snack for a great white, shark attacks have long been a real fear for beachgoers. While attacks and fatalities look to be on the rise, scientists are yet to pinpoint exactly why.

A single vertebra dug out of a rock in a stream below a New Zealand mountain in 1978 has been found to have belonged to the oldest sea reptile in southern waters, where no record of these huge beasts had existed. It dates back 246 million years.

For four years, orcas have been ramming and sinking luxury yachts, and scientists finally have an idea why. No, it's not their anticapitalist 'eat the rich' agenda, nor is it to do with territory and aggression. The truth is, well, it's child's play.

The infamous mantis shrimp is in possession of a club-shaped claw that can deliver fatal blows to everything from hard-shelled prey to thick aquarium glass. So what happens when they thump a fellow mantis shrimp foe? Thanks to science, we now know.

A newly described species of marine reptile could be the largest to ever swim the world’s oceans. The “giant fish lizard” lived more than 200 million years ago, and may give the blue whale a run for its money, size-wise.

An underwater expedition off the coast of Chile has discovered 160 species not known to live in the region, at least 50 of which are new to science. The information will inform marine protection strategies for important regions in international waters.
