Significance To Humans

Human food source (adductor muscle), harvested by native populations on Pacific Islands. Shells historically used for making tools (mallets, hoes, scrapers); also used intact as water basins (and in churches worldwide as baptismal fonts, suggested by the French vernacular name). Non-nacreous pearls have little commercial value, although the largest pearl on record is the oblong "Pearl of Allah," 9 in (22.9 cm) long and 14 lbs (6.35 kg) in weight, from a T. gigas specimen collected in the Philippines in 1934. ♦
