What has the best eyesight in nature?

The compound eyes of the mantis shrimp are considered to have the best eyesight in nature. They possess up to 16 types of photoreceptor cells, allowing them to see a spectrum of colors far beyond human capability, including ultraviolet light. This extraordinary vision aids them in communication and hunting in their vibrant underwater environments. Their ability to perceive polarized light also enhances their ability to detect prey and predators.
