The eyes of a Peacock Mantis Shrimp (Odontodactylus scyllarus), which are mounted on stems, are independently mobile and highly developed. Due to the relatively small field of vision, of a Peacock Mantis Shrimp keep their eyes constantly moving to observe their surroundings.
The compound eyes of a Peacock Mantis Shrimp are usually divided into three parts: They consist of an upper section, a median strip (usually six rows of ommatidia wide) and a lower section.
Due to the shape of the eyes, the fields of view of the upper and lower sections overlap, as can also be seen from the recognizable pseudopupils.
This enables separate spatial vision with each complex eye. Eyes that are not subdivided have e.g. Neogonodactylus curacaoensis.
The ommatidia of the median are specialized in the perception of different light qualities. Some species differentiate between up to 12 color channels, some in the UV range, and can differentiate differently polarized light, including circularly polarized light.
The surroundings are perceived in the overlapping visual area by each eye on several channels in parallel (spatial, color, UV, polarization).
Peacock Mantis Shrimp can use the perception of the sky polarization pattern to orientate themselves in their habitat.
