An emotional memorial for Plett shark attack victim Kimon Bosogno was held this weekend, once again raising fears and concerns about shark, their movement and presence close to shore at our popular beaches. Lester Kiewit speaks to Dr Enrico Gennari, marine ecologist specialising in white sharks, from the Oceans Research Institute in Mossel Bay says we should not panic because people are not the natural prey of sharks, and they are not actively seeking us out.
