Peacock mantis shrimp (Odontodactylus scyllaru). The mantis shrimp has one of the most elaborate visual systems ever discovered. Compared to the three types of colour-receptive cones that humans possess in their eyes, the eyes of a mantis shrimp carry 16 types of colour receptive cones. Furthermore, some of these shrimp can tune the sensitivity of their long-wavelength vision to adapt to their environment. The midband region of its eye is made up of six rows of specialised ommatidia—a cluster of photoreceptor cells 12 for colour sensitivity, 4 for colour filtering. The vision of the mantis shrimp can perceive both polarised light and multispectral images. Their eyes mounted on mobile stalks and capable of moving independently of each other are similarly variably coloured and are considered to be the most complex eyes in the animal kingdom.
