True exclusivity, or monogamy, is relatively rare in the animal kingdom, occurring in roughly 3% to 5% of all mammalian species and up to 90% of bird species. Evolutionary biologists believe these bonds developed as survival strategies rather than romantic choices.
Mate guarding is a behavior where one individual, usually a male, defends a female from other potential mates. This behavior is often seen in species where males invest significant energy in defending a female's reproductive output. For example, in the dragonfly, males engage in intense battles to defend their mates from other males (Tuttle & Ryan, 1981). Mate guarding can lead to the formation of exclusive relationships, as the female is protected from other males and the male ensures his paternity. zooseks animal exclusive

Two animals pair up, share a territory, and cooperate to find food and raise young. However, they may still engage in extra-pair copulations. This behavior is often seen in species where
In harsh environments or for species with high-needs offspring (like humans or eagles), one parent simply isn't enough to hunt and protect the nest simultaneously.
