What does the Mako's large brain-to-body size ratio proxy for in comparative biology?

Greater processing power dedicated to sensory integration and problem-solving

The brain-to-body size ratio is frequently employed in comparative biology as an indicator anticipating higher levels of cognitive function. When an animal dedicates a larger percentage of its mass to its brain compared to the rest of its physical structure, it implies that more neurological resources are available for complex operations beyond basic motor control and survival reflexes. For the Mako shark, this measurement suggests advanced capabilities in integrating diverse sensory inputs—such as vision, lateral line input, and chemoreception—and using that integrated information to formulate effective solutions, such as successful predatory strategies or navigating large, fluctuating environments. This proportional measurement is key to hypothesizing about the dedication of neural architecture toward complex thought processes.
