Mantis shrimp have some of the most complex eyes in the animal kingdom. Here are a few features that make their eyes extraordinary:
Trinocular Vision: Mantis shrimp have trinocular vision, which means they have a separate eye for each of the three parts of their eyes: one for detecting colors, one for detecting motion, and one for detecting polarized light. This gives them the ability to perceive depth and distances extremely accurately.
Complex Color Vision: Mantis shrimp have complex eyes capable of detecting a wider spectrum of colors than humans. While humans have three types of photoreceptor cells for color vision (red, green, and blue cones), mantis shrimp have between 12 and 16 types of photoreceptor cells. Some species can see ultraviolet light, far-red light and polarized light, which is light vibrating in a specific direction.
Independently Moving Eyes: Each eye can move independently, allowing them to scan their surroundings without moving their bodies. This ability gives them excellent situational awareness and helps them spot predators and prey quickly.
Rapid Eye Movements: Mantis shrimp can move their eyes incredibly quickly, making rapid eye movements to track fast-moving prey or avoid predators effectively.
Polarized Light Detection: Mantis shrimp can also detect polarized light patterns, which are invisible to the human eye. This ability helps them communicate with each other using polarized light signals, as well as detect prey and predators.
Protective Mechanisms: Mantis shrimp eyes are well-protected and are capable of sophisticated adaptations. Some species can retract their eyes into sockets, while others have hardened, calcified shields that protect their eyes during fights.
The remarkable features of mantis shrimp eyes have fascinated scientists for years and continue to be a subject of intense research in the fields of optics and vision science.
