The only known animals with just one eye are tiny, swimming crustaceans called copepods.
Copepods swim in short bursts by moving their long, branching antennae. Most kinds filter their food from the water, eating algae, protozoa, or bacteria. They are the most abundant animals in the ocean, and they are a very important part of the plankton food chain. In actual numbers, there are far more copepods in Earth's oceans than there are insects on land!
The most common kind of copepod is called the Cyclops, named after the mythical, one-eyed giant.

There are three kinds of men. The ones that learn by reading. The few
who learn by observation. The rest of them have to pee on the electric
fence for themselves
