The group of conchs that are sometimes referred to as "true conchs" are marine gastropod molluscs in the family Strombidae, specifically in the genus Strombus and other closely related genera. For example, see Lobatus gigas, the queen conch, and Laevistrombus canarium, the dog conch.
Many other species are also often called "conch", but are not at all closely related to the family Strombidae, including Melongena species (family Melongenidae), and the horse conch Triplofusus papillosus (family Fasciolariidae). Species commonly referred to as conchs also include the sacred chank or more correctly shankha shell (Turbinella pyrum) and other Turbinella species in the family Turbinellidae.
The English word "conch" is attested in Middle English, coming from Latin concha (shellfish, mussel), which in turn comes from Greek konchē (same meaning) ultimately from Proto-Indo-European root *konkho-, cognate with Sanskrit śaṅkha.
Conch is most indigenous to the Bahamas, and is typically served in fritter, salad, and soup forms. Conch is also eaten in the West Indies (Jamaica in particular); locals in Jamaica eat conch in soups, stews, and curries. Restaurants all over the islands serve this particular meat. In the Dominican Republic, Grenada, and Haiti, conch is commonly eaten in curries or in a spicy soup. It is locally referred to as lambi. In the Turks and Caicos Islands, the Annual Conch Festival is held in November each year, located at the Three Queens Bar/Restaurant in Blue Hills. Local restaurateurs compete for the best and most original conch dishes, which are then judged by international chefs. Free sampling of the dishes follows the judging; along with those festivities, other competitions, events, and music performances occur well into the evening. In Puerto Rico, conch is served as a ceviche, often called ensalada de carrucho (conch salad), consisting of raw conch marinated in lime juice, olive oil, vinegar, garlic, green peppers, and onions. It is also used to fill empanadas.
Conch is very popular in Italy and among Italian Americans. Called scungille (pl. scungilli), it is eaten in a variety of ways, but most often in salads or cooked in a sauce for pasta. It is often included as one of the dishes prepared for the Feast of the Seven Fishes.
Eighty-percent of the queen conch meat in international trade is imported into the United States. The Florida Keys were a major source of queen conchs until the 1970s, but the conchs are now scarce and all harvesting of them in Florida waters is prohibited.
Conch shells can be used as wind instruments. They are prepared by cutting a hole in the spire of the shell near the apex, and then blowing into the shell as if it were a trumpet, as in blowing horn. Sometimes, a mouthpiece is used, but some shell trumpets are blown without one. Pitch is adjusted by moving one's hand in and out of the aperture; the deeper the hand, the lower the note.
Various species of large marine gastropod shells can be turned into "blowing shells", but some of the best-known species used are the sacred chank or shankha Turbinella pyrum, the Triton's trumpet Charonia tritonis, and the queen conch Strombus gigas.
Many different kinds of mollusks can produce pearls. Pearls from the queen conch, S. gigas, are rare and have been collectors' items since Victorian times. Conch pearls occur in a range of hues, including white, brown, and orange, with many intermediate shades, but pink is the colour most associated with the conch pearl, such that these pearls are sometimes referred to simply as "pink pearls". In some gemological texts, non-nacreous gastropod pearls used to be referred to as "calcareous concretions" because they were "porcellaneous" (shiny and ceramic-like in appearance), rather than "nacreous" (with a pearly lustre), sometimes known as "orient". The GIA and CIBJO now simply use the term "pearl"—or, where appropriate, the more descriptive term "non-nacreous pearl"—when referring to such items, and under Federal Trade Commission rules, various mollusc pearls may be referred to as "pearls" without qualification.
Although not nacreous, the surfaces of fine conch pearls have a unique and attractive appearance of their own. The microstructure of conch pearls comprises partly aligned bundles of microcrystalline fibres that create a shimmering, slightly iridescent effect known as "flame structure". The effect is a form of chatoyancy, caused by the interaction of light rays with the microcrystals in the pearl's surface, and it somewhat resembles moiré silk.
- Conch shells are sometimes used as decoration, as decorative planters, and in cameo making.
- In classic Maya art, conchs are shown being used in many ways, including as paint and ink holders for elite scribes, as bugles or trumpets, and as hand weapons (held by combatants by inserting their hands in the aperture).
- Conch shells have been used as shell money in several cultures.
- Some American Aboriginals used cylindrical conch columella beads as part of breastplates and other personal adornment.
- In India, the Bengali bride-to-be is adorned with conch shell and coral bangles called shakha paula. It is an important wedding ritual for every Bengali bride, as it is an integral Bengali tradition."
- In some Afro-Caribbean and African-American cemeteries, conch shells are placed on graves.
- In some Caribbean countries such as Jamaica and the Bahamas, cleaned queen conch shells, or polished fragments, are sold, mainly to tourists, as souvenirs or in jewelry. Responding to a 2003 recommendation from CITES, some countries in the Caribbean have banned the export of queen conch shells. CITES has also asked all countries to ban import of these shells from countries that are not complying with CITES recommendations for managing the fishery. Queen conch fisheries have been closed in several countries. Conch shells or fragments taken home by tourists from noncomplying countries may be confiscated on return to the tourist's home country while clearing customs. In the UK, conch shells are the 9th-most seized import.
- Conch shells are occasionally used as a building material, either in place of bricks, or as bulk for landfill.
- In Grenada, fishermen use the conch shell as a trumpet to announce to the community that fish is available for sale. Conchs are used at carnival times in the Jouvert Jump where Diab Diab (Jab Jab) blow conch shells as part of the festivities. Especially in Guadeloupe, hearing conch shells being blown near ports at dawn and during Carnival times, too, is not uncommon. Many bands are making the conch shell a main instrument.
- In the Bahamas, broken or up-turned conch shells are imbedded into the tops of outdoor walls in an effort to maintain home security; these shells are sharp enough to cut any intruder who attempts to jump or crawl over the wall.
- In Tamil Nadu, India, the conch horn is blown during funerals as an acoustic indication of the funeral and to ward off evil spirits.
- In Key West, Florida, a native-born résident is affectionately called a "conch".
A shankha shell (the shell of a T. pyrum, a species in the gastropod family Turbinellidae) is often referred to in the West as a conch shell, or a chank shell. This shell is used as an important ritual object in Hinduism. The shell is used as a ceremonial trumpet, as part of religious practices, for example puja. The chank trumpet is sounded during worship at specific points, accompanied by ceremonial bells and singing. As it is an auspicious instrument, it is of purity and brilliance (Om, Devas, Brahman the Almighty Supreme creator, referred to in mantras, the Gayatri mantra explains a meditation on the brilliance of the sun), it is often played in a Lakshmi puja in temple or at home.
In the story of Dhruva, the divine conch plays a special part. The warriors of ancient India blew conch shells to announce battle, as is described in the beginning of the war of Kurukshetra, in the Mahabharata, the famous Hindu epic.
The god of preservation, Vishnu, is said to hold a special conch, Panchajanya, that represents life, as it has come out of life-giving waters. An interesting story is behind the origin of a shankha or conch shell. According to Hindu mythology, Devas (Gods) and Asuras (Demons) once decided to churn the ocean to get a special divine nectar. This divine nectar also known as amrit was known to give immortality to whoever drank it. All the Gods were on one side of it and the Demons were on the other end. The Samudra Manthan produced a number of things from the ocean. One of the first things to come out of it was lethal poison called halahala. Everyone was terrified, as the poison was potent enough to destroy entire creation, so they went to Lord Shiva for protection and he consumed the poison to safeguard the universe. Lord Shiva took the poison in his mouth, but did not swallow it. Shankha also was one of divine objects that was obtained from Samudra manthan.
Also, the sound of the conch is believed to drive away the evil spirits. The blowing of the conch or "the shankha" needs a tremendous power and respiratory capacity. Hence, blowing it daily helps keep the lungs healthy.
A newlywed Bengali bride wears bangles called shakha paula, made from coral and conch-shell powder. They have been a part of Bengali custom and tradition. In an ancient era, the Bengali farming community is thought to have resided near the river. They collected conch shells and powdered them to create bangles. They also used red coral for the bangles. They gave these beautiful bangles to their wives, as they could not afford ivory bangles. They were also known as poor-man's ivory, as they were cheap substitute for ivory bangles.
Literature and the oral tradition
- The famous Old English riddle Ic wæs be Sonde describes a conch: "I was by sound, near seawall, at ocean-stream; I dwelt alone in my first resting place... Little did I know that I, ere or since, ever should speak mouthless over mead-benches." Another meaning given to this riddle "Ic wæs be Sonde" is that the sound of the conch corresponds to spiritualised sound as heard in higher realms. In the Hindu tradition, the conch shell is used in ceremony as the sound it makes is said to correspond with higher frequency universal sounds associated with music of the spheres.
- William Golding's novel Lord of the Flies (1954) features frequent references to "the conch". In the book, the conch is used as a trumpet to call everyone together and held by whoever is speaking at meetings, symbolically representing democracy and order. The conch is seen as a delicate and beautiful object to represent this concept, although its fragility is shown when it "exploded into a thousand white fragments and ceased to exist".
- Ostional, a pueblo in the municipality of San Juan del Sur in the Rivas Department of the southwest region of Nicaragua, by accounts of multiple testimonials in the local region, was founded by their ancestors because of an abundant conch population at the seashore. Subsequently, the tribe used conch shells in many rituals and customs. In 2008, witnesses at local archaeological digs reported conch shells were found in the graves of some indigenous people in their recently rediscovered cemetery grounds. Some still maintained jade stones, implying the significance of conch shells within their tribal society.
