You’ve probably seen the viral infographics. They show a human looking at a rainbow, then a mantis shrimp looking at some psychedelic, neon explosion that looks like a 1960s Grateful Dead poster. People love to say these creatures see a "world we can’t even imagine" because they have 12 to 16 color receptors compared to our measly three. But honestly? Most of those viral graphics are kind of a lie. When we talk about mantis shrimp vision simulation, we aren't just talking about adding more colors to a photo. We're talking about a completely different way of processing reality that actually makes their color perception worse than ours in some ways, even while it detects things like cancer and satellite signals.
It's weird. Evolution usually moves toward efficiency. Yet, here is this "shrimp" (which is actually a stomatopod, not a true shrimp) rocking a visual system so complex it makes a Leica camera look like a toy.
The 12-Channel Myth and the Reality of Processing
If you have a red, green, and blue receptor, your brain does math. It compares the signals. This is called "opponent processing." If the "red" sensor is firing hard and the "green" one is firing a little bit, your brain says, "Okay, that's orange." We can see millions of shades because we interpolate.
Scientists like Hanne Thoen and Justin Marshall at the University of Queensland decided to actually test this. They didn't just look at the eyes; they ran behavioral experiments. They rewarded the mantis shrimp for striking certain colors. What they found was shocking: mantis shrimp are actually pretty bad at telling similar colors apart. If you show them two shades of light orange, they can't tell the difference, whereas a human could.
So why the 12 receptors? Basically, they don't do the math. Instead of comparing signals to create a spectrum, their eyes seem to work like a "barcode scanner." They have a dedicated sensor for a specific wavelength. It's faster. It's low-energy. For a creature that needs to punch a crab at the speed of a .22 caliber bullet, speed matters more than aesthetic nuance. A mantis shrimp vision simulation shouldn't look like a more vibrant rainbow; it should look like a hyper-efficient, high-contrast motion detector.
Seeing the "Invisible" With Circular Polarization
This is where the technology gets genuinely sci-fi. Humans see color. Some birds and bees see ultraviolet. But mantis shrimp see circular polarized light (CPL). This is extremely rare in nature.
Light waves normally wiggle in all directions. Polarized light wiggles in one plane (like what your sunglasses filter). Circularly polarized light spins like a corkscrew. Mantis shrimp can see this spin. Why? Because many of their favorite snacks are transparent or camouflaged. However, organic tissues reflect CPL differently.
In a modern mantis shrimp vision simulation used in laboratory settings, researchers use "bio-inspired" sensors to "see" what the shrimp sees. They've discovered that cancerous tissue often reflects polarized light differently than healthy tissue. By mimicking the stomatopod’s eye, doctors can potentially spot the borders of a tumor that are invisible to the naked eye. It’s not about seeing "prettier" colors; it's about seeing structural data.
The Midband: The Eye Within an Eye
If you look at a mantis shrimp, their eyes are stalks that move independently. Across the middle of each eye is a "midband." This is where the magic happens.

- The top and bottom hemispheres see shapes and motion.
- The midband (six rows of specialized ommatidia) handles the color and the polarization.
- Because each eye has three distinct sections, a mantis shrimp has trinocular vision in a single eye. They have depth perception even if they lose an entire eye.
How We Actually Simulate This (The Tech Side)
Creating a mantis shrimp vision simulation isn't just a Photoshop filter. It requires a "polarization camera." Viktor Gruev at the University of Illinois at Urbana-Champaign has been a leader in this. His team developed a sensor that mimics the vertical integration of the mantis shrimp's eye.
Instead of a flat sensor, they use stacked nanowires. This allows the camera to capture the "Stokes parameters" of light—basically a mathematical description of its polarization state. When we "watch" a simulation of this, the software usually maps the polarization data to colors we can see. For instance, light spinning clockwise might be rendered as bright red, and counter-clockwise as bright blue.
It looks trippy, but for a surgeon or a satellite operator, it's functional data. In underwater environments, this simulation allows us to see through murky water. Silt and debris scatter light in predictable ways, but a polarization-sensitive "shrimp eye" camera can filter that noise out to see a clear image of a submarine or a coral reef.
Why the Internet Gets the "Rainbow" Wrong
We have this human-centric bias. We think "more receptors = more beauty." But for the mantis shrimp, the world is likely a series of high-intensity flashes and specific "target" signatures.
Imagine you're a fighter pilot. You don't want to see a beautiful sunset; you want the Head-Up Display (HUD) to highlight the enemy jet in bright green. That’s the mantis shrimp. Their world is a HUD. When we try to create a mantis shrimp vision simulation, we are trying to build a biological computer vision system.
They see UV-A and UV-B. They see deep reds that we can't touch. But they don't see them as "extra" colors. They see them as specific signals. It's been suggested that they use these colors for secret communication. Some species have patches on their shells that reflect UV or polarized light. To a predator, they look drab. To a mate, they are glowing like a neon sign in Vegas.
Practical Applications You Can Use Today
While you can't buy "shrimp glasses" at the mall yet, the research into mantis shrimp vision simulation is already affecting how we interact with the world.
If you're a photographer, you’re already using a tiny fraction of this tech when you use a circular polarizer (CPL filter) on your lens to cut glare from water. But the next level is "multispectral imaging." Companies are now developing smartphone sensors that use more than three channels (RGB). Imagine a phone that can tell if a piece of fruit is ripe or if a mole on your arm looks suspicious just by analyzing the light "shrimp-style."

Actionable Steps to Explore This Further
- Check out the "Stomatopod Vision" databases: Search for the work of Roy Caldwell at UC Berkeley. He’s the "godfather" of mantis shrimp research and has some of the best actual footage of how these animals react to light.
- Experiment with Polarization: If you have two pairs of polarized sunglasses, overlap them and rotate one. You'll see the light vanish. That’s a basic look at how light can be "tuned," which is what the shrimp does naturally.
- Follow Bio-Inspired Robotics: Look into the Wyss Institute at Harvard. They are constantly publishing papers on how "shrimp-eye" sensors are being integrated into autonomous vehicles to help them "see" through fog and rain where LiDAR fails.
- Download Spectral Apps: There are apps that attempt to simulate various forms of color blindness and animal vision. While none perfectly capture the 12-channel barcode system, they help break the habit of thinking our "human" view is the only "correct" one.
The reality of the mantis shrimp isn't that they see a "better" world. It's that they see a "hidden" one. They've traded the ability to see a sunset's subtle gradient for the ability to see the very fabric of light itself. It's a trade-off that has kept them alive for 400 million years, long before humans even stepped onto the scene.
By studying mantis shrimp vision simulation, we aren't just learning about a weird crustacean. We're learning how to build cameras that can find landmines, detect skin cancer early, and navigate the dark corners of the ocean. It's not a rainbow. It's a superpower.
Next Steps for Enthusiasts:
If you want to see the actual data visualizations, look for "Polarization-sensitive CMOS sensors" in academic journals like Optica. These contain the closest thing we have to a "shrimp-view" video. You can also look up the species Odontodactylus scyllarus (the Peacock Mantis Shrimp) to see the specific anatomy of the midband that makes this all possible.
