Pentachromate

A pentachromat (Greek five-color seer ) is a living being that can perceive five different primary colors .

The physiological explanation for pentachromatia is that the retina is equipped with at least five different photoreceptors ( cones ).

In lampreys the type pouched lamprey five different color receptors and the associated were visual pigments demonstrated. Some birds , e.g. B. pigeons and mallards as well as butterflies are likely pentachromats.
