Drone pics may be first-ever images of a newborn great white shark

Hard though it may be to believe, there has apparently never been a confirmed sighting of a live newborn great white shark. Such may no longer be the case, however, thanks to recently analyzed aerial drone footage shot in California.Continue ReadingCat… Continue reading Drone pics may be first-ever images of a newborn great white shark

Megalodon may have been longer than we thought, claims new study

Most of us picture the megalodon as a Jason-Statham-hunting monster that looked like a giant great white shark, but that probably wasn’t the case. A new study re-examines fossil evidence and suggests the creature was longer and more slender than we tho… Continue reading Megalodon may have been longer than we thought, claims new study

Roots of life: The 2023 Mangrove Photography Award winners

Mangroves may not be the first thing you picture when you think ‘forest’, but they’re both incredible, unique ecosystems and serve as a kind of structural and water-quality coastguard. And while mangrove forests make up about 0.1% of the planet’s surfa… Continue reading Roots of life: The 2023 Mangrove Photography Award winners

Megalodon was warm-blooded – and that might have been its downfall

Fossilized teeth are most of the remains we have today of the megalodon, which makes it hard to figure out what it looked like or how it lived. But now, scientists have used those teeth to estimate the ancient shark’s body temperature, and found it was… Continue reading Megalodon was warm-blooded – and that might have been its downfall

Hammerheads hold their breath to keep warm when deep-diving for food

Researchers at the University of Hawai’i at Mānoa have made a surprising first discovery: scalloped hammerhead sharks hold their breath like air-breathing marine mammals when they deep dive into cold waters to feed. The finding has improved our underst… Continue reading Hammerheads hold their breath to keep warm when deep-diving for food

Device uses a BAT signal to show where sharks are giving birth

The majority of shark species are threatened with extinction, so it’s crucial to protect the “pupping” areas where females give birth to live young. A new satellite-linked device, known as the BAT, lets scientists know the locations of those areas.Cont… Continue reading Device uses a BAT signal to show where sharks are giving birth

Device generates electrical fields to keep sharks away from fish hooks

It’s a sad fact that threatened species of sharks are routinely caught on fishing lines intended for other types of fish. A new device could help change that, by harmlessly scaring sharks away from baited hooks via pulses of electricity.Continue Readin… Continue reading Device generates electrical fields to keep sharks away from fish hooks
