Recent studies of dolphins have revealed some startling biological facts and some significant details of dolphin society. Dolphins have few natural enemies and as a result spend much of their time playing. Most of their play is sexual making dolphins the only animal other than man who indulges in sex for pleasure as well as for reproduction. From sea aquariums where dolphins are taught to perform for the public, to the laboratory where scientists are trying to determine the limits of dolphin intelligence, dolphins develop special relationships with the humans who work with them.
