conch

The shells of large marine gastropods are blown into as if they were natural instruments, as in blowing instrument. A completely unmodified conch may be used, or a mouth hole may be created. Wooden, bamboo, metal, or any kind of material used to make mouthpieces may be inserted into the end of the shell. Embouchure is used to produce notes from the harmonic series. A tone hole may be added to change the fundamental frequency but globally this is extremely rare. Various species of large marine gastropod shells can be turned into "blowing shells", but some of the more commonly used species include triton ('natural instruments shell'), cassis ('helmet shell') and strombus ('true conch')."
