Detailed explanation-1: -animal social behaviour, the suite of interactions that occur between two or more individual animals, usually of the same species, when they form simple aggregations, cooperate in sexual or parental behaviour, engage in disputes over territory and access to mates, or simply communicate across space.

Detailed explanation-2: -One example of how social behavior is adaptive is aggregation against predators. This concept applies to caterpillars feeding together on a leaf, a herd of wildebeest, schools of fish, and flocks of birds. A landscape filled with solitary wildebeest will offer easy pickings for large predators such as lions (Figure 2).

Detailed explanation-3: -Social behavior characterizes the interactions that occur among individuals. These can be aggressive, mutualistic, cooperative, altruistic, and parental.

Detailed explanation-4: -Living in social groups is clearly beneficial for many species, often resulting in increased survival, enhanced fitness of the group, and progression of brain development and cognitive abilities.
