Why are pterosaurs different from each other?

Pterosaurs vary widely due to their adaptation to different ecological niches and environments. Factors such as size, wing shape, and feeding strategies contribute to their diversity; for instance, some were large gliders suited for long-distance travel, while others were smaller and more maneuverable, ideal for hunting in dense vegetation. Additionally, evolutionary pressures, such as predation and competition, influenced their physical traits and behaviors, leading to the broad range of pterosaur species observed.
