Trochus is a genus of medium-sized to very large sea snails. They are marine gastropod molluscs in the family Trochidae, the top snails.
Trochus niloticus, for example, is a very large (up to 13 cm) Indo-Pacific top shell, which has a very thick inner layer of nacre. This species is commercially exploited to make mother of pearl buttons, mother of pearl beads, pendants and so on.
