SPECIES: Haliaeetus leucocephalus
I CAN SEE A MOUSE FROM A HEIGHT OF 6,500 FEET
Nobody could pull the wool over these eyes: The vision of Haliaeetus leucocephalus is among the sharpest of any animal! Its visual acuity is four to eight times as strong as that of a human, enabling it to spot a small dormouse from 6,500 feet away without any problem, for example. Its secret: Its retinas have five times more visual cells than ours ( about 1,000,000 cone cells per each mm2). The concentration of photoreceptor cells is particularly high in the fovea centralis pits of its retinas, which is ideal for prey-location purposes. The extremely high density of cone cells also enables this predator to see its quarry in the water from a distance of up to 2,600 feet away. The result: Its catch rate is a recordbreaking 90%. Such an incredible performance ability makes it the undisputed king of all fishermen…
