WHEN YOU SEE SOMETHING UTTERLY SHOCKING, IT MAY FEEL LIKE YOU CAN'T LOOK AWAY. BUT FOR OWLS, THE INABILITY TO AVERT ONE'S EYES IS MORE OF A BIOLOGICAL RESTRAINT THAN MORBID CURIOSITY. OWLS CAN ONLY SHIFT THEIR PEEPERS ABOUT 3 DEGREES IN ANY DIRECTION (ROUGHLY 1/15TH THE DEGREE OF MOVEMENT HUMAN EYES HAVE), AS AN OWL'S EYES ARE ESSENTIALLY LOCKED IN PLACE.
THIS IMMOBILITY IS DUE TO THE OWL'S LACK OF SPHERICAL EYEBALLS, WHICH HAVE A GOOD RANGE OF MOTION AND ARE PRESENT IN MANY OTHER ANIMALS. INSTEAD, AN OWL'S EYES ARE SHAPED MORE LIKE ROD-SHAPED TUBES, AND THEY'RE HELD FIRM BY BONY FACIAL STRUCTURES CALLED SCLEROTIC RINGS. DESPITE THE LIMITATION, OWLS STILL HAVE A FULL 360-DEGREE FIELD OF VISION, AS THEY CAN EASILY ROTATE THEIR NECKS 270 DEGREES HORIZONTALLY AND 90 DEGREES VERTICALLY.
