Ever wondered why mantis shrimp are the kings and queens of the underwater vision world? Well I’m about to blow your mind with some incredible facts about these little creatures’ amazing eyes! As someone who’s been studying marine life for years I can tell you – these guys are truly spectacular.
The Basics: How Many Cones Do Mantis Shrimp Actually Have?
Let’s cut straight to the chase – mantis shrimp have up to 16 different photoreceptors! Compare that to us humans with our measly three photoreceptors (red, green, and blue), and you’ll see why scientists are so excited about these creatures.
Breaking Down the Numbers:
- 12 cones for color vision
- 4 additional photoreceptors for:
- UV light detection
- Polarized light sensing
- Circular polarized light detection
Why So Many Cones?
You might think “Wow with 16 photoreceptors, these little guys must see colors amazingly well!” But here’s the funny thing – they’re actually pretty bad at distinguishing between similar colors! Let me explain why
Human vs. Mantis Shrimp Vision:
-
Humans (3 cones):
- Process colors through complex neural networks
- Compare signals between different cones
- Better at distinguishing similar colors
-
Mantis Shrimp (16 cones):
- Process colors independently
- Quick color recognition
- Less accurate at color discrimination
The Superpowers They Actually Have
So what’s the point of all those extra cones? Well, these little warriors have some pretty cool tricks up their sleeves:
- UV Vision: They can see ultraviolet light that’s invisible to us
- Polarized Light Detection: They’re like walking around with built-in polarized sunglasses
- Depth Perception: They can judge distance with just ONE eye (how cool is that?)
- Independent Eye Movement: Each eye can move separately (like a chameleon!)
The Eye Structure: It’s All About That Mid-band
The secret sauce of mantis shrimp vision lies in their eye structure. Here’s what makes it special:
- Compound eyes with thousands of tiny units (ommatidia)
- 6 rows of specialized ommatidia in the mid-band
- First 4 rows handle visible and UV light
- Last 2 rows deal with polarized light
Real-World Applications
Scientists aren’t just studying mantis shrimp eyes for fun! Their unique vision system is inspiring some pretty cool tech:
- Better DVD and Blu-ray technology
- Advanced camera systems
- New types of polarized sunglasses
- Improved satellite communications
My Personal Take
I gotta say, as someone who’s written about marine life for years, mantis shrimp never cease to amaze me. While they might not be the best at distinguishing between your navy blue and royal blue shirts, they’ve evolved this incredible system for quick color recognition that helps them survive in their coral reef homes.
Tips for Spotting Mantis Shrimp
If you’re lucky enough to go diving and want to spot one of these vision champions, here’s what to look for:
- Check coral reef areas
- Look for small burrows in the reef
- Watch for quick, colorful movements
- Be careful – they pack a mean punch!
Final Thoughts
The mantis shrimp’s 16 cones might seem like overkill, but nature knows what it’s doing! These creatures have developed exactly what they need for their survival, even if it works differently than we might expect. It’s a perfect example of how evolution doesn’t always follow our human logic – and that’s what makes it so fascinating!
Remember folks, sometimes more isn’t better – it’s just different! The mantis shrimp proves that having 16 cones doesn’t necessarily mean better color vision, but it sure makes for one incredible creature!

Why are mantis shrimp eyes so special?
Mantis shrimp are famous for two things. First, they pack a tremendous punch, wielding clubs on the end of their front limbs that can accelerate as fast as a bullet in a gun barrel. Second, they possess what are widely regarded as the most complex eyes of any animal.
As with many st, mantis shrimp sport a pair of compound eyes on stalks. And, like those of flies, they are composed of thousands of ommatidia – individual lenses and retinas that each sample a tiny area of the field of view.
But mantis shrimp eyes are capable of rotating independently and in three dimensions like angle-poise lamps. They can also perceive distance using a single eye, because multiple ommatidia focus on the same point. The extraordinary optical system of the Peacock Mantis Shrimp. Credit: Getty
What does the mantis shrimp see?
FAQ
Do mantis shrimp have 16 cones?
What does the world look like from the eyes of a mantis shrimp? With as many as 16 types of colour-sensitive cone cells in their retinas (humans have three), their colour vision capabilities surpass those of any other animal.
What animal has 12 cones?
New studies suggest that mantis shrimp vision might not be as advanced as once believed. They do have up to 12 photoreceptors — the cells in the retina that respond to light. (Humans only have 3.)
How many light cones do shrimp have?
The mantis shrimp have twelve to sixteen color-receptive cones. They see color so much.May 13, 2024
How many hearts does a mantis shrimp have?
The single-chambered heart is enclosed in a pericardial sinus and is located dorsally, above the gut.
How many color-receptive cones does a mantis shrimp have?
Humans have three types of color-receptive cones—green, blue and red—that form the basis of how we perceive all color. The mantis shrimp has 16types of color-receptive cones. That means the way it processes light and color is beyond anything we can imagine.
How many photoreceptors does a mantis shrimp have?
With 16 photoreceptors to humans’ three, mantis shrimp see the bigger picture. Credit: DiverKen As humans, we experience an amazing world of colour, but what can other animals see? Some see much more than us, but how they use this vision is largely unknown. We see what we see because our eyes have three photoreceptors, red, green and blue.
How many ommatidia does a mantis shrimp have?
Mantis shrimp have compound eyes that are made up of tens of thousands of ommatidia (elements containing a cluster of photoreceptor cells, support cells and pigment cells) much like flies. In the species with spectacular vision, Gonodactylids and Lysiosquillids, the middle of the eye has six rows of modified ommatidia called the mid-band.
Do mantis shrimp have eyesight?
As if its predatory prowess wasn’t enough, the mantis shrimp is also endowed with incredible eyesight. Humans have three types of color-receptive cones—green, blue and red—that form the basis of how we perceive all color. The mantis shrimp has 16types of color-receptive cones.
Are mantis shrimp able to distinguish colors?
Humans also have an incredibly precise and accurate ability to distinguish and identify between colors. Remarkably, despite having about 4 times as many photoreceptors as humans, mantis shrimp are actually rather poor at discriminating between colors.
How much light can a mantis shrimp see?
This allows them to see not only the entire visible spectrum seen by humans (400 to 700 nanometer wavelengths), but also some light in the ultraviolet and infrared range, beyond human visual capacity. In essence, mantis shrimps can process light in the range of 300 to 720 nanometers (nm), and in this lies their advantage .
