How do meerkats know when predators are coming?

Meerkats have a highly developed system of communication and vigilance that helps them detect predators. They take turns acting as sentinels, standing on elevated spots to watch for danger while the rest of the group forages. These sentinels use specific alarms and body language to alert others when a predator is approaching, allowing the group to react quickly and find safety. Their keen eyesight and social structure enhance their ability to spot threats early.
