In the ocean, hammerhead sharks prowl with some of the most amazing eyes in the natural world.
The bizarre head that gives this predator its name...has been the source of fascination...and bewilderment.
Theories abound. Many believe the head evolved as a kind of specialized rudder...allowing the shark to whip its body quickly upwards, backwards...and side to side.
It appears the shark does use its shape to facilitate lightning fast agility in the water.
But what may be even more useful to this graceful carnivore is vision from eyes at the very edge of the head's wide hammer.
Eyes that can see...nearly everything around them.
With eyes spread wide, the shark has spectacular vision.
With a move to the right, the shark can even see far behind.
With a move to the left...the same.
In fact, these eyes are positioned to give the hammerhead panoramic vision.
