Their number and shape vary based on the diet of the fish: widely spaced gill rakers are evident on fish that eat large prey, such as other fish, which prevent the prey item from getting free and escaping between the gills. To get enough oxygen the fish must make water flow across its gills. Because there's more oxygen in the water than in the blood, the oxygen diffuses through the gills into the animal. It involves the fish opening and closing its mouth to draw water over the gills. Having so many tiny secondary lamellae creates an enormous surface area for oxygen to be absorbed through.
