Dietary indiscretion is the tendency of certain animal of eating unusual items. These are frequently relatively small items not encountered in a natural habitat and thus sampled because of mistaken identity, a familiar flavor, or simple curiosity. This includes modern manufactured items such as shiny metal foil or plastic objects, as well as foods harmful to health. Domesticated animals such as dogs and goats, and even circus animals like Ostriches are even more prone to the effect due to their contact with people. The dietary indiscretion of fish, especially Sharks, may occur when the mouth is the major organ of detection and processing.
