What did evolutionary pressure favor in the Mako more than in other shark types?

Neural complexity

The relative investment in brain size for the Shortfin Mako suggests a specific direction of evolutionary pressure acting upon the species. While many sharks might thrive by evolving adaptations that maximize brute physical strength, highly specialized external sensory organs, or extremely large body sizes for physical dominance, the Mako's proportional brain size indicates that selection favored the development and sophistication of its nervous system. This emphasis on neural complexity suggests an adaptive advantage derived from superior processing power, complex behavioral flexibility, and effective integration of diverse sensory information over relying primarily on extreme physical traits or social aggregation.
