Sharks are virtually synonymous with carnivorousness, but the bonnethead shark, as new research suggests, is a true flexitarian, capable of switching between meat and plant-based diets.

Researchers working in Africa are the first to observe monkeys preying on bats. The unusual behavior, which may have something to do with loss of habitat, could explain how dangerous diseases such as Ebola spread among species—and eventually to humans.

Like hummingbirds, Australian rainbow lorikeets eat pollen and nectar. In fact, they have a specialized tongue that allows them to do so. So imagine the surprise of bird experts after discovering of a population of lorikeets who have taken to eating meat.

Ever wondered just where humans fall on the food chain? Wonder no more. Researchers have calculated our precise location (somewhere right next a pig or an anchovy, apparently), along with another surprising trend: While we're firmly omnivores, we're also becoming more and more carnivorous.
