The mating calls túngara frogs make have an unfortunate side effect: attracting one of their main predators.

"There's mounting evidence that different species pay attention to each other in the wild, especially if they share predators."

To steer clear of predators like orcas, right whales tone down their vocalizations, which "can be thought of almost like a human whisper."

New research finds that reef fish populations depend on two things: good hiding spots and a resident predator.

When wild animals get sick, they can't go to the drug store or a vet. Predators may be the best solution for keeping herds healthy.

Groups of giraffes that include calves make different choices about where to spend time than all-adult groups, mainly to avoid predators.

"There are many different ways of communication in biology but this is really a new kind of signaling between cells that we're trying to understand."

"Chasmaporthetes probably hunted herds of ice age caribou and horses or scavenged carcasses of mammoths on the vast steppe-tundra..."

Although chimpanzees mostly stick to a vegetarian diet, those in the rainforest also catch and eat crabs.
