Mantis shrimp's supercolor vision debunked
Mantis shrimp colors: how many colors can mantis shrimp see? The mantis shrimp colors, a species of shrimp, have been trained to recognize ten specific color wavelengths, ranging from 400 to 650 nanometers. The shrimp can discriminate between their trained wavelengths and another color 50-100 nanometres up or down the spectrum. However, when the difference between the trained and test wavelengths was reduced to 12-25 nanometres, the shrimp could no longer tell them apart.
The shrimp eye, which has 12 receptors, is less sensitive than the human eye but does not require brain-power-heavy comparisons. This may give the predatory shrimp a speed advantage in distinguishing between different-colored prey. The study is an important step towards understanding the complexity of the mantis-shrimp eye and the brain’s use of visual signals.

Different Color Recognition Needs and Approaches
The mantis shrimp has found a shortcut to color processing by utilizing its large number of photoreceptors. These shrimp can pick up complex colors without merging multiple sources of information, allowing them to process them unconsciously.
This processing allows humans to think about colors before seeing them, but it also means that our consciousness is slightly behind what is happening in the real world. Our view of the world is always slightly behind reality due to the slow processes our brains process from our eyes. This is not the case for the mantis shrimp, as they live in a world shaped by similar slow processes. This makes it possible for the shrimp to see the present and experience complex colors without the need for conscious thought.

Different visions for different life paces
Mantis shrimp, with their powerful speed and complex color vision, can move at 50 mph and break through aquariums. This unique color vision bypasses the neurological legwork of humans, allowing them to see complex colors more quickly. This allows them to catch their prey faster and react to them more quickly than competing predators. While some may argue that a shrimp’s supervision is a myth, it’s important to remember that vision is more than just color combinations. Mantis shrimp’s eyes still have some surprising surprises to offer us.
Unique interaction with ultraviolet light
Mantis shrimp, known for their ultraviolet sensitivity, have six photoreceptors that detect light in the ultraviolet range. However, only two opsins are sensitive to ultraviolet light. This is due to a crystalline structure above each photoreceptor, which contains mycosporine-like amino acids (MAAs). These MAAs can block or filter UV light, allowing the shrimp to react to color more quickly. This allows the shrimp to conserve resources and avoid unnecessary biological waste.
Consolidating information for a clear answer
Mantis shrimp‘s vision is peculiar, making it difficult to make accurate comparisons to other animals. Their eyes are not just about their photoreceptors, but also their neurological differences. The human brain handles most color perception, while the mantis shrimp’s biology focuses on avoiding the neurological processing of visual data.
While they can see into ranges that humans cannot, their ability to use that data is considerably lacking. The mantis shrimp’s view of color is alien to humans and is distinct from most other forms of life on Earth. Science is still developing a better understanding of their vision, but each new discovery will contribute to understanding the nature of color perception.
