Eland antelopes use their knees to get a leg up on rivals, according to researchers working in Kenya. When mature bulls walk, their knee tendons slip over their leg bones, making a clicking sound like castanets. The noise, which can be heard hundreds of yards away, may help maintain dominance hierarchies: the louder the tone, the bigger the bull. The downside? Lions can hear it, too.
