How big were megalodon gills?

Megalodon, the prehistoric shark, is believed to have had gills that were quite large, potentially measuring around 1 meter (3 feet) in length. These formidable gills would have allowed the massive creature, which could reach lengths of up to 60 feet, to efficiently extract oxygen from water, supporting its immense size and active predatory lifestyle. While exact measurements are difficult to determine, the gills were proportionate to its size, enabling it to thrive in the oceanic environment.
