It's the iconic movie scene. People are enjoying a leisurely swim, canoe trip or boat ride across the sea when they suddenly spot a singular fin bobbing above the water. Next thing they know, they're surrounded by sharks just metres away from them - and the sharks are heading their way.
These films are often set in far flung locations, but the fact is that sharks can also be found swimming in Welsh waters. According to SharkTrust, there are more than 40 species of sharks that swim around the coast of Britain each year - with at least 21 of those living in British waters all year round. Whilst you're unlikely to come across a shark on a day trip to your local beach, although that has happened at Caswell Bay, you could come across empty egg-cases washed up along the strandline or see a shark or two if you're far-out at sea.
That said, living in Wales, you're very unlikely to come across a great white! Great whites are typically found off the coasts of southern Australia, New Zealand, southern Africa and parts of the US, although one was spotted just yards from a UK beach - you can read more about that here.
