Optical illusions are always entertaining because they challenge how discerning and perceptive our eyes actually are. On first look, the image above appears to be completely filled with orange crabs and adorable orange clownfish swimming about in unison. Their identical figures and vibrant orange hues immediately deceive the mind into thinking that the whole image consists of the same design. But it is not. Concealed among these fishes and crabs is a sneaky starfish, and your task is to find it in 7 seconds.

The magic of this trick is based on the matching colours. Because the starfish is orange as well, it is perfectly camouflaged among the clownfish and the crabs, so it is really difficult to find in a short time. Our brain groups similar shapes and colours together. This causes us to ignore the tiny differences when confronted with a horizon of doppelgangers. That is why most individuals will look at the image and still not notice the starfish right away.To overcome this problem, slow down and take a methodical look at the photo rather than allowing your eyes to scurry across it. Attempt to distinguish differences of outline rather than colour. Although the clownfish possess fins, tails, and rounded forms, the starfish possesses a completely different outline with five pointed arms. After you are able to shift focus to searching for a different outline, the concealed starfish will begin to stand out.So, are you ready to put your observation skills to the test? Begin the countdown, 7 seconds on the clock, and attempt to see the starfish before time expires.If you succeed, hooray! You really do have a keen pair of eyes. And if you didn’t, don’t worry. Optical illusions such as these are intended to deceive even the keenest observers. The starfish is there in plain sight, cunningly disguised among the fishes.
