Recreating 130,000 years of mammal food webs with machine learning reveals the scope of the biodiversity crisis.

Just about every creature on Earth needs to grab some Zs from time to time. Imagine trying to doze while dodging great whites and killer whales.

The megalodon was an even more fearsome predator than previously thought, able to take down prey the size of modern orcas.

Urban coyotes prey on rodents and spread plant seeds. It’s OK to observe them from a distance, but then you should chase them off.

Megalodon, the world’s largest known shark species, swam the oceans long before humans existed. Its teeth are all that’s left, and they tell a story of an apex predator that vanished.

Animals are altering their lives to adapt to climate change, but those changes may make them worse off, researchers warn.

Once hated, native predators are now credited with limiting invasive prey populations.

Hanging out with other guppies can offer protection against predators, but all that social mingling can set them up for breeding deadly parasites.

A species of jumping spider in Kenya appears to use the blood-red abdomen of mosquitoes to target them as prey.

Researchers have discovered that great white sharks are more social than previously thought. Using specialized tags, they tracked six sharks and found that some stay close to each other when hunting.
