People used to think I was crazy," says Lonu Ahmed. Even my mum thought I was insane. Fishermen used to beg me not to dive with sharks."

Ahmed lives on the island of Fuvahmulah in the Maldives, an island surrounded by tiger sharks. The islanders have traditionally been terrified of the creatures: fishermen would regularly kill them. Ten years ago, however, believing the sharks were misunderstood, Ahmed jumped into the water, to the horror of onlookers. He says he saw something they didn't.
