What about sea birds and color vision?
When you swim underwater in the ocean you need to wear goggles. Salt water is dangerous for human eyes.
But not for birds; sea birds have excellent vision and good color vision, too.
Seabirds don’t need goggles! They fly high above the surface of the ocean looking for food. Far below them, in the water, they can see the colors and the movements of the fish. They dive straight down into
their ocean and catch their dinner. They never miss because their color vision is so good.
dive ( verb ) to jump into water with your arms and head going in first miss ( verb ) to fall to hit, catch, reach or get something
