It was the last hour of the last day of Peter Smith's holiday in Tobago when he decided to take a dip in the sea. The conditions were perfect for a swim, the retired IT director recalls. I dived into the waves, swam out no more than 20 feet (6m), and stood waist-deep in the water. He and his wife Joanna, from Hertfordshire, were away with friends, and the last thing on their minds was the risk of shark attacks - they are unheard of on this tiny Caribbean island.

Suddenly I felt a very heavy object hit my leg. I look down and there's a shark - and it's big, Peter says. You're talking maybe 10 foot (3m). That's when your brain works at 1,000 miles an hour. He had been bitten by a bull shark, one of the most dangerous in the world.

In his first interview since the attack, Peter explains how he was bitten on his leg, then on his arm and stomach, losing significant blood. Thankfully, friends nearby helped him out of the water, where he received urgent medical attention. After several operations, he reflects on his survival, grateful for his mobility and vowing not to let fear dictate his life.

Peter’s experience is a stark reminder of the risks present in nature but also highlights the rarity of such incidents and the importance of appreciating the ocean without fear.
