Pearl Divers dive without external oxygen sources in search of oysters containing pearls. How far can other creatures dive in their search for adventure or food? This graphic shows you how deep certain animals dive.
Natural pearls, the kind of pearls harvested from oysters by pearl divers, came in a variety of shapes and sizes – and were difficult to find – making them expensive and rare. Cultured pearls, those produced with the help of human intervention, were pioneered by the Japanese with Mikimoto patenting his technique for producing spherical cultured pearls around 1916. Today the vast majority of pearls sold are cultured pearls because they are easier to produce and are less expensive than natural pearls.
