Sexual Size Dimorphism

Sexual Size Dimorphism refers to differences in size between males and females of the same species. These differences often arise due to reproductive roles or competition, where, for example, males may be larger to compete for mates or defend territory, or females may be larger for producing and caring for offspring. It is common in many animals, including birds, mammals, and insects. The degree of size difference varies widely across species and is influenced by environmental factors, evolutionary pressures, and behavioral strategies, helping species adapt to their specific reproductive and survival needs.
