There's nothing like a brain teaser to force your mind to wake up on a Sunday morning. By completing these puzzles regularly we're also able to improve our cognitive abilities, memory and even overall brain health.
If you're looking for a brain teaser to really test your skills, we've got the one for you. In this scuba diving scene there are four mistakes hidden – and it's your job to find them.
In the image, you'll see two divers exploring in the ocean, and they are surrounded by fish – and even a dolphin.
On first glance it may seem like nothing is out of the ordinary – but this is where you need to focus your mind. You'll need to really look carefully to see the mistakes among all the underwater activity.
To make it even harder, JagranJosh is challenging you to spot all four mistakes within 13 seconds. Only those with a high IQ manage to do it within the time limit, according to the publication.
If you can't spot all the mistakes within the allotted time, don't worry too much. Take your time and see if you can find them.
If you're still struggling, we've posted the answers below. So consider this your spoiler warning.
There are four mistakes hidden within the picture – and not all of them are obvious.
Firstly, the female scuba diver has a bottle instead of a breathing cylinder on her back.
The second mistake is that the dolphin has only one fin. Number three – the word SOS has been written in the sand under water, which wouldn't be possible.
Lastly, there's also a butterfly under the see, which is located in the top right hand corner with the fishes.
