Ruminants – including the largest species of antelope and deer – must remain vigilant for predators despite the continual chewing that mars their hearing. Visual monitoring of their companions’ mouths allows them to notice any individual that suspiciously stops chewing. Previously unnoticed by zoologists are the dark and pale markings accentuating the lips and lower jaw in the common eland and the moose, which potentially aid this collective vigilance.
