Because of this it actually can see to some extent what is going on behind be-hind it The rodent family, of which the hare is a member, have eye arrangements with divergences of visual axes from 50 degrees to 170 degrees between both eyes. Nearest to man come the carni-vorae, carni-vorae, which include the cat and dog. The lion has a divergence of only 10 degrees in eye movement, and the cat has about 18 degrees. Eyes of dogs are set with 30 to 50 degrees of divergence between them. Pigs have divergence of 66 degrees; cows, 104; camels, 124, and giraffes, 144. |
