Megalodon’s teeth evolved over 12 millions years, researchers find

This is not the Nemo you’re looking for.

Great white shark genome might teach us how to heal faster or stave off cancer

Scientists sink their teeth in the great white’s genome

Paleontologists discovered a new species of ancient shark — and it was so, so tiny

“[Its] teeth are the size of a sand grain. Without a microscope you’d just throw them away,” says one of its discoverers.

Megalodon may have been warm-blooded — and this may have ultimately doomed the huge predator

The largest fish in history may have been doomed by its active metabolism that couldn’t keep up with a tough ice age.

Scientists find the first plant-eating shark — but it still likes to hunt

A ferocious predator actually enjoys a vegetarian snack from time to time.

Scientists find deep-sea miniature shark that glows in the dark

We’ve just started discovering the tip of the iceberg in terms of deep sea creatures.

Bamboo sharks really have to put their back into eating — literally

Specifically, they put their shoulders into it.

New ancient car-sized species identified by paleontologists. It was related to Megalodon

Some 20 million years ago, both the Atlantic and the Pacific were haunted by a huge shark the size of a car.

Fossil Friday: Helicoprion

Helicoprion is an extinct genus of shark-like, cartilaginous fish that lived from the early Permian (~290 m.y. ago) all through to the massive Permian-Triassic extinction episode (roughly 250 m.y. ago.)

How many friends would a shark have on facebook?

Sharks have a reputation of solitary predators. They’re not the life of the party, sort to say. One new research casts doubt on this assumption, though. The findings suggest that sharks, or at least Sand Tiger sharks, have a complex social structure not all that different in some instances from notoriously social mammals like dolphins, chimps or even humans.

Some deep-water sharks can float up, contrary to conventional wisdom

Researchers at University of Hawaii, Manoa in collaboration with a team from the University of Tokyo were surprised to find not one, but two species of deep-water sharks that have positive buoyancy. Most sharks have a negative buoyancy, meaning if they stop swimming they’ll sink to the bottom, and some researchers have posited that there may be some species with neutral buoyancy. Finding sharks that defy this conventional wisdom is definitely an important discovery. Now the researchers are trying to find out how the positive buoyancy is attained and whether other shark species have this ability.

Sharks act like Math Geniuses

At least in one aspect, sharks behave as world class mathematicians – although the cause may be sensibleness more than cleverness. The behavior associated to both mathematicians and sharks is called the Lévy flight. A Lévy flight is a random walk in which the step-lengths have a probability distribution that is heavy-tailed. In other words, it’s a seemingly complex form of random
