Justine,
We all hear about shark attacks and that makes us very nervous. My son who is about your age gets worried too. However, the shark attacks we hear about usually happen in the United States where the ocean water is much colder than the ocean in Aruba. Sharks do not like warm water and that is why they stay far out in the middle of the ocean. We have been coming to Aruba for years and have never heard of anyone having an encounter with a shark. Enjoy the ocean, it is wonderful.
