        Aquariums in many large cities, such as New York,
        Chicago, San Diego, Waikiki, London, and Sydney, have
        impressive shark displays, and most can provide comprehensive
        background information in the form of books and leaflets,
        photographs, lectures, and Web sites. Conservation organizations,
        such as the Shark Research Institute, also provide information
        about sharks and encourage young people to get involved. There
        are also programs where people can adopt a shark and find out
        about its progress.
           The best way to learn about sharks is to see them in the
        wild. Sharks live in all oceans of the world but only a few
        kinds are found in polar waters. You can see some sharks from
        boats including basking sharks and even great white sharks.
        Learning how to snorkel and scuba dive will also give many
        opportunities to see sharks, such as reef sharks that live in
        tropical waters. Check first that any boat tour or dive trip to
        see sharks meets with conservation guidelines.

                         Shark cages are designed for
                         protection against larger
                         sharks—smaller species can
                         slip through the gaps.
