Conch shells have been played as trumpets from Ice Age caves to Grenada's fish markets
Cut a hole near the tip of a large sea snail's shell and it becomes a horn; push your hand deeper into the opening and the note drops. A shell found in a Pyrenees cave in 1932 had been fitted with a mouthpiece by ancient people, and researchers with a horn player managed to sound it again.
Conch is a loose label for several medium to large sea snails whose shells taper to a point at both ends. True conches belong to the family Strombidae, including the queen conch, but the name also covers unrelated animals such as the horse conch and the sacred chank of India. The shells are roughly 95 percent calcium carbonate, and the English word traces back through Latin to Greek, with a Sanskrit cousin in shankha.
Blowing a conch carries meaning in many places. For the Aztecs it featured in ritual, war, music and even the calendar, and the wind god Quetzalcoatl wore a conch jewel on his chest. Bengali Hindu households sound one each evening, and brides wear conch and coral bangles. In Japan the horagai was blown at ceremonies such as royal cremations in the Edo period, while in Grenada fishermen still use one to announce a catch for sale. Hawaiians long used the shell for signalling, and in the Caribbean broken shells are set along wall tops to deter intruders.
Queen conch pearls are rare and prized, mostly pink, and lack the nacre of oyster pearls. Instead, bundles of tiny aligned fibres give their surface a shimmering pattern called flame structure, resembling moiré silk.
Appetite has taken a toll. Conch fritters, which Time called the Bahamas' original fast food, and Caribbean salads, stews and curries rely on queen conch, and the United States imports eighty percent of the international trade in its meat. The Florida Keys were a major source until the 1970s; harvesting there is now banned, and in 2024 the species was listed as threatened under the Endangered Species Act. Several Caribbean nations stopped exporting the shells after a 2003 CITES recommendation, and conch shells rank ninth among imports seized in the UK.
