To communicate with each other, hyenas smear pastelike secretions on grasses from a fist-size gland beneath their tails. Other hyenas that sample these leavings can sniff a wealth of information, including the animal's sex, social status, willingness to mate and more. But the hyenas themselves do not produce these scents — they are actually the product of bacteria that live in the animals' scent glands, a new study shows. As bacterial communities within scent glands change and evolve, so do the odiferous compounds that waft forth, said Kevin Theis, lead author of the study and an ecologist at Michigan State University.

Much like some people I know
