There Are 4 Animals Hidden In This Image - But Only A Special Few Can See Them All

This new optical illusion image has been making the rounds of the web! Optical illusion images, which are images that fool the brain, seem to be very popular on the internet, which seems to be the ideal platform to share these kinds of images. For example, this one is known as the McCollough effect, in which colourless lines appear coloured.

Optical illusions are often difficult to define, because why they are caused is not often clear. However, the most standard definition is that it is caused by the visual system, by a perception that appears to differ from reality. Animal optical illusions seem to be among the most popular recently, such as this one in which an 'invisible leopard' drove internet users crazy. What some people see in other optical illusions on the other hand can even depend on their age! In any case, the popularity of these images is in no way waning.

In this new image, a landscape can be seen in which there are no less than 4 animals hidden, but not everyone can see them. Experts say that only those who have a high IQ can see them all: it's a real test of intelligence!
