Prehistoric claw marks found inside Australia's Tight Entrance cave reveal a bit more about the continent's extinct predator, the marsupial lion. It turns out the animals were agile hunters that reared their young inside the cave.
Much like people living in packed cities, it may be now that animals of prey in Africa have a smaller number of offspring when living in crowded conditions. Turns out, this is affecting lions and other predators.
Tropical songbirds have a lower adult mortality rate than temperate birds because they are raised in smaller families. This directly affects their wing growth and ability to escape from predators.
Well, not quite. But new remarkable research has shown that in the longest ever tiger tracking study, these predators boast migration patterns more similar to birds, turtles and some marine mammals than other fishes.
With flashbacks to Jaws in mind, it seems like an insane idea to leave the safety of a diving cage with a massive great white shark swimming just a few feet away. And yet that's exactly what one lucky diver did near Guadalupe Island in Mexico.
The fossilized remains of a gigantic, 20-foot shark - the size of a two-story building and over 100 million years old - have been unearthed in Texas.
We all know about the boy who cried wolf, but a new study sheds light on brown thornbills, tiny birds that "cry hawk" to escape from predators.
Today's snakes are known for slithering on the ground, but new surprising research says that the first snakes on Earth were likely stealthy predators that boasted legs, ankles, and even toes.
Fish are known for being seemingly cold-hearted creatures, swimming the cool depths of our vast oceans. But now scientists have discovered the first fully warm-blooded fish, and it's making them question how much we really know about marine life.
Ants are pretty clever insects, with researchers recently finding that certain species can even double their survival rate using impressive jaw jumps.
We all know that the age of the dinosaurs must have been a hostile time on Earth, and now there's proof, as scientists have recently discovered evidence of bloody dino battles that took place.
An ancient and unusual lobster-like predator was recently discovered in Canada, in a fossil treasure trove dating as far back as 508 million years ago - well before the first dinosaurs walked the Earth, according to a new study.
Scientists have discovered what they call a "super salamander" species in Portugal that was a top predator more than 200 million years ago, and it just may be one of the strangest creatures to ever terrorize the Earth.
Scientists have just discovered a new 9-foot-long crocodilian ancestor that was once one of North America's top predators, dominating the Earth before dinosaurs came on the scene, new research indicates.
