Sharks
-
For the first time ever, a lone orca has been observed killing and eating a great white shark. Although orcas were already known to hunt great whites in packs or pairs, one had never been seen going solo before. The finding suggests the emergence of a new hunting strategy.
-
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.
-
Most of us picture 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 thought.

Mangroves may not be the first thing that comes to mind when you think of a forest, but they're both incredible, unique ecosystems and serve as a structural and water-cleaning coastguard. These photos capture the wondrous, otherworldly ecosystems.

In the third BMC Ecology and Evolution image competition, a stunning snap of the invasive orange pore fungus (Favolaschia calocera) has not just encroached on native species’ territory but taken out the top spot in the annual contest.
-
Scientists have used fossilized megalodon teeth to estimate the ancient shark’s body temperature, and found it wasn’t exactly a cold-blooded killer. Strangely enough, that might have contributed to its downfall.
-
In a surprising first, researchers found that scalloped hammerhead sharks act like air-breathing marine mammals, holding their breath to stay warm when they deep-dive into cold water for food and making them vulnerable to humanity's deep-sea exploits.
-
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.
-
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.
-
Back in July, we heard how orcas were hunting great white sharks in South Africa. While scientists were basing their findings on examinations of shark carcasses, they've now gained new insights by analyzing aerial video of a hunt in action.
-
Even though the basking shark is the world's second-largest fish, much of its life has eluded observation. Now, however, researchers have determined that the usually solitary animals find mates by meeting up and circling around one another.
-
By combining cutting-edge digital modeling with analysis of a rare, one-of-a-kind fossil, scientists have managed to piece together the first 3D reconstruction of the megalodon, the largest shark to ever live.
