Horses have the largest eyes of any land mammal.
When horses look like they’re laughing, they’re actually engaging in a special nose-enhancing technique known as “flehmen,” to determine whether a smell is good or bad.
At one time people thought horses were colorblind. They’re not, though they are better at seeing yellows and greens than purples and violets.
In 1872, Leland Stanford (1824-1893) made a bet that at some point in the gallop all four of a horse’s legs are off the ground at the same time. Eadweard Muybridge (1830-1904) proved him right by using a series of 24 cameras and photographing a racehorse named Sallie Gardner.
