Mantis shrimp can distinguish light in unusual ways using many photoreceptor types. Unlike our three-channel color system, it uses a more segmented spectral sampling.
Underwater, colors play by different rules. Water filters light, turning vision into an evolutionary competition.
Mantis shrimp eyes carry many receptor types tuned to different wavelengths. That can help it sort light into more categories.
Their visual systems also show remarkable sensitivity to polarized light. This can shape behavior from communication to hunting.
The animal inspires biomimetic sensor designs. Nature can treat vision as information richness, not only sharpness.
