Have any animals evolved an odd number of eyes?

Starfish have an eye at the end of each leg. A five legged starfish will have five eyes. They can have as many as twenty legs, each with its own eye.

We can add a few more to the list. There long extinct ancestors of fish that had a third eye. A remnant of this eye can be found in some lizards, tadpoles and other amphibians. Many species of jellyfish and shellfish have a great many eyes. Some of them will be an odd number I'm sure.

A small crustacean commonly called a "tadpole" or "tadpole shrimp" has three eyes. It's scientific name is triops-cancriformis. Triops means "three eyes".

Many flying insects such as bees, flies and dragonflies have two main compound eyes, but also have three simple eyes or ocelli on top of their heads which detect light rather than seeing in any detail.
