predators

Historically, coyotes roamed a broad expanse, as far east as the Mississippi and as far west as the Pacific, north into Canada and south into Mexico, but since 1900 they’ve extended their range into every corner of the US

The stripes on some insects help them survive in the wild. When prey with high-contrast stripes move, their stripes blur, making it hard for a predator to see them. That's what a group of scientists found out in an experiment on praying mantises.
