What animal can see 16 colors? The mantis shrimp is renowned for its extraordinary vision, capable of detecting 16 different color channels, compared to the three that humans can perceive. This unique ability allows the mantis shrimp to see a spectrum of colors that are invisible to the human eye, providing them with exceptional visual capabilities in their underwater environment.
How Does a Mantis Shrimp’s Vision Work?
The mantis shrimp’s vision is a result of its complex eye structure. Unlike humans, who have three types of photoreceptor cells, mantis shrimp have 12 to 16 types of photoreceptors. These additional photoreceptors enable them to detect a wider range of colors, including ultraviolet light.
- Photoreceptors: Mantis shrimp possess multiple photoreceptors, each sensitive to different wavelengths of light.
- Ultraviolet Detection: They can see ultraviolet light, which is beyond human perception.
- Polarized Light: Mantis shrimp can also detect polarized light, which is useful for hunting and communication.
Why Do Mantis Shrimps Need Such Complex Vision?
The mantis shrimp’s habitat and lifestyle necessitate their advanced visual system. Living in vibrant coral reefs, these creatures rely on their vision for various survival tasks.
- Hunting: Their ability to see a wide range of colors and polarized light helps them spot prey hidden among the coral.
- Communication: Mantis shrimp use their colorful body patterns to communicate with each other, and their vision allows them to interpret these signals effectively.
- Predator Avoidance: Detecting subtle changes in light and color can help them evade predators.
How Does Mantis Shrimp Vision Compare to Human Vision?
To better understand the mantis shrimp’s visual capabilities, let’s compare them to human vision in a table format.
| Feature | Mantis Shrimp | Humans |
|---|---|---|
| Color Channels | 12-16 | 3 |
| Ultraviolet Vision | Yes | No |
| Polarized Light | Yes | No |
| Depth Perception | Limited | Advanced |
Can Mantis Shrimps See Better Than Humans?
While mantis shrimps have more color channels, their vision isn’t necessarily "better" than humans in all aspects. Humans excel in depth perception and have a more integrated visual processing system, allowing for complex image interpretation.
What Are the Practical Applications of Studying Mantis Shrimp Vision?
Research into mantis shrimp vision has inspired technological advancements and scientific insights.
- Optical Devices: Their ability to detect polarized light has influenced the development of advanced optical devices and cameras.
- Biomedical Research: Understanding their vision could lead to innovations in medical imaging techniques.
- Robotics: Mantis shrimp vision principles are being applied to improve robotic vision systems.

What Other Animals Have Unique Vision?
Other animals with unique vision include birds of prey, which have keen eyesight for spotting prey from great distances, and chameleons, which can move their eyes independently to scan their surroundings.
How Do Mantis Shrimps Use Polarized Light?
Mantis shrimps use polarized light detection to navigate their environment, communicate with other shrimps, and locate prey, as polarized light can reveal hidden objects in water.
Are Mantis Shrimps Dangerous?
Yes, mantis shrimps can be dangerous due to their powerful claws, which they use to strike with incredible speed, capable of breaking shells or even aquarium glass.
How Do Mantis Shrimps Communicate?
Mantis shrimps communicate using body language and color displays, which are enhanced by their ability to see a broad spectrum of colors, including ultraviolet light.
What Is the Lifespan of a Mantis Shrimp?
Mantis shrimps can live for up to 20 years in the wild, depending on the species and environmental conditions.
Conclusion
The mantis shrimp, with its ability to see 16 colors, offers a fascinating glimpse into the diverse world of animal vision. While their visual system is uniquely adapted to their underwater habitat, it also serves as an inspiration for technological advancements. Understanding these creatures not only enriches our knowledge of marine biology but also drives innovation in various scientific fields.
