For millions of years, the apex predator of the oceans was a bus-sized shark known as the Megalodon. But around 2.6 million years ago they just disappeared. So what could wipe out a 50-ft (15-m) shark? According to a new study, the culprit was a series of supernovae exploding fairly close to Earth.

It's well reported that oil spills can have a catastrophic biological and environmental impact. But to date, few studies have examined the effect of whole crude oil on senses of a marine vertebrate. A new study is the first to confirm effects on stingrays' sense of smell.

Anglerfish are famous for their head-mounted bulbs that light up the inky blackness of the deepest oceans, but to find out exactly how, Cornell researchers have now sequenced the genome of the bacteria that live inside those lightbulbs, and found a strange story of symbiosis still in progress.

When scientists are using submersibles to study deep-sea organisms, it's understandable that they'd want to harmlessly capture fragile-bodied animals in order to get a closer look at them. Well, Harvard University's Rotary Actuated Dodecahedron (RAD) sampler is designed for just such a purpose.

If you don't like seeing sea creatures getting saddled with cumbersome, uncomfortable-looking data-tracking devices, then you might like Marine Skin. While it still allows scientists to gather important data, it's also thin, light, flexible, stretchable and streamlined.

Camouflage allows soldiers to blend into their surroundings, but what if they could adapt to different surroundings in seconds? A team of researchers at Northeastern University has turned to cephalopods in an attempt to uncover their camouflage secrets and see if they can be mimicked.

Scientists from the Marine Biological Laboratory and the University of Cambridge have found that the cuttlefish controls its stealth ability using a giant neural circuit that similar to the one that squids use to control their iridescence.
