California Sea Lion
The Eyes Have
The mountain lion--also known as cougar, painter, puma, panther, or catamount--is one of three native cats in the Pacific region of the United States.
The mountain lion is a nocturnal predator and has excellent hearing and vision. Its eyes are well-adapted for night vision. Its pupils are large with many rods for gathering light. Behind the retina of each eye is a reflective membrane called the tapetum lucidum. The tapetum lucidum reflects light back through the retina, giving it a second chance to absorb the light. This reflection is the glow you can see in any cat's eyes at night.
Like most predators, the mountain lion's eyes point forward and are placed close together. This provides binocular vision, which allows the animal to judge depth and distance accurately.
