things i didn't know, latest in a series

Via Mike, I learned something about meerkats today: they don’t wear headphones.

Meerkats demonstrate altruistic behavior within their colonies; one or more meerkats stand sentry (lookout) while others are foraging or playing, to warn them of approaching dangers. When a predator is spotted, the meerkat performing as sentry gives a warning bark, and other members of the gang will run and hide in one of the many bolt holes they have spread across their territory. The sentry meerkat is the first to reappear from the burrow and search for predators, constantly barking to keep the others underground. If there is no threat, the sentry meerkat stops signaling and the others feel safe to emerge.

Who’s your meerkat?
