People who hated Jaws growing up... look away now!
A man who was training for a charity swim off the coast of England encountered the stuff of nightmares this week.
Oly Rush was 240 feet away from the coast of Dorset when he felt something brushing his leg.
He looked down and spotted the terrifying site of a whole pod of smooth hound sharks.
They circled him for around 15 minutes while nibbling at his hands and feet- which we imagine would you freak you out.
This was at midnight, when Oly set off- and couldn't see more than a few metres ahead.
His pal Ashley McPherson was accompanying him on a kayak, as he felt the nudges to his legs- and Ashley shone a torch on the scene to get a better look.
The pair eventually counted 50 sharks- but Oly was not phased.
He said: "Before we set off I had joked about being attacked by sharks and we were laughing about it.
"It was my first night-time swim, so it was pretty unnerving when I suddenly came up against something in the water.
"Then things started to nibble at my hands and feet, the parts which weren't covered by my wet suit..
"When I realised what it was I just enjoyed the experience - it was fantastic to see so many sharks in the wild just behaving naturally and in such good health. I felt very privileged.
"After about 15 minutes I swam on and left them to it. I think they might have been attracted to a flashing light in my tow float that I swim with.
"The sharks' nibbles didn't hurt because they don't have teeth."
