Sharks

Although it's not a hard and fast rule, marine animals that live in cold climates tend to grow larger than their warm-water counterparts. According to a new study, such may have true for everyone's favorite prehistoric shark, the megalodon.

Zero-emissions airliners are still a long way off, but Lufthansa and BASF have developed a way to improve things right now. AeroShark is an adhesive riblet film that immediately reduces fuel consumption, and therefore emissions, from any aircraft.

In most depictions of the extinct megalodon shark, it looks pretty much like a super-sized version of its modern relative, the great white. According to a new study, however, it may actually have been considerably less similar in appearance.

Back in 2019, we heard how scientists at Australia's Flinders University were developing a lightweight material that might someday be used in shark-bite-resistant wetsuits. Well, that day has arrived, and such a suit is now on Kickstarter.

If you've seen even a single shark documentary, then you've probably heard that the majority of attacks on humans are likely due to sharks mistaking people for seals. Scientists now say they've confirmed that theory, using computer models.

They might hold a reputation as one of the ocean's most ruthless predators, but new research has shown that different species of sharks can actually go to some lengths to keep peace in the seas by doing their hunting in shifts.

Sharks have been around a long time, so it should come as no surprise to hear that even the first humans had run-ins with them. Scientists have now discovered evidence of the earliest-known such attack, which occurred 3,000 years ago in Japan.

Scientists have discovered a hitherto unknown mass extinction event that decimated the global shark population some 19 million years ago. The study authors say the event saw sharks almost entirely disappear from the open ocean in its wake.

The whale shark and the manta ray are perhaps two of the ocean's most fascinating large fishes. Well, scientists have now announced the discovery of a prehistoric ancestor of both, that looked like a cross between the two.

The great white shark may be one of the ocean's top predators, but it's still affected by climate change, just like any other animal. That's what's indicated by a new study, which shows that young great whites in California are moving to the north.

Scientists examining shark and ray populations across the globe have published an alarming study depicting a rapid decline of these species over the past half century, with the blame mostly resting at the feet of unsustainable fishing practices.

Sharks pre-date even the earliest dinosaurs, so it's not surprising to hear that they've changed over the years. It was recently discovered, for instance, that they were once able to rotate the two sides of their jaw outwards, helping them to feed.
