In nature most of the organisms work independently to conduct their basic daily activities like searching for food and protecting themselves from predators. But there are few organisms in nature that live in a group, and there is a division of work between them. For example in Meerkats (a small carnivore mammal belonging to the mongoose family) one or more of them stand sentry, to warn others of approaching dangers while others are busy finding the food. When a predator is spotted, the meerkat performing as sentry gives a warning bark or whistle. Female meerkats that have never produced offspring of their own often babysit the young in the group. Such behavior is also observed in many types of insects like bees, wasps, termites and in ants. Such types of animals are called Eusocial animals. In this video, worker ants are carrying the eggs to a safer place after the colony was disturbed by human moment.
