An optical illusion featuring two water buffalos has gone viral after sharp-eyed viewers spotted a hidden animal.

We’re back with another perplexing picture challenge that will put your observation skills to the ultimate test. Your task today is to take a close look at the graphic below and answer one simple question.

How many animals can you see in the image?

Take your time if you hope to answer this puzzle correctly.

There are clearly two black water buffalos with white patches on their heads grazing in the picture. But they are not alone. There is a third animal and most people can’t find it without help.

Since our eyes are trained to focus on darker shades first, we often forget to pay attention to what’s hiding in the negative space – the white background and other bright areas in this case.

To spot the third animal – a big white cow – focus on the white space between the two black water buffalos. Did the third figure finally emerge?

As you can see, three animals were hiding in the picture this entire time!
