Description Presented here is a vast gallery of many different forms of Optical Illusions. Whether these optical illusions are conveyed through fractals, photographs, architecture, art, or old fashioned pen and ink, they are bound to remind you that "seeing is not believing."

Caution!!!! Some of the optical illusions on this blog may cause dizziness or possibly epileptic seizures. The latter happens when the brain can't handle the conflicting information from your two eyes. If you start feeling unwell when using this website, immediately cover one eye with your hand and then leave the page. Do not close your eyes because that can make the attack worse.

Spot the Fish Optical Illusion

I love this little animated image (found here). It illustrates how camouflage works in nature. When the little critters are moving they can be seen but often when they are still they blend into the background and seemingly disappear.

Below is an image taken by Dory English he calls "Spot The Fish". Dory sent this to me after he saw this post on camouflage optical illusions in nature.

Can you spot the fish? This is an example of once an animal that uses camouflage for protection comes to rest it is very difficult to see.

move mouse over image for solution

My 11 year old daughter assisted my old eyes in spotting this fish. She even suggested That I outline it so it would be easier for you to find, but what fun would that be? Let me just say that the fish is positioned tail left, head right and the yellow dot is the eye of the fish. Update: I took my daughter's advice, just move your mouse over the image for the solution.

This fish while moving (like the animated image above) can be seen easily, but once it comes to rest it blends into it's environment and is very hard to spot.

This is an excellent example of Mother Nature employing an optical illusion to protect one of her own. Thanks Dory for sending this to me and allowing it's inclusion in this gallery of illusions.
