Trivia is a genus of small sea snails, marine gastropod molluscs in the family Triviidae, the trivias.[1]
These are known in Britain as "cowries". The shell of these species does superficially resemble the shell of a very small cowry, but Trivia species are not very closely related to true cowries.
Species
The genus Trivia has recently been split into many genera, including Cleotrivia, Niveria, Pusula, Triviella, Trivirostra etc., but this information is not yet shown completely in the species list below. There is currently no consensus about definition of the genera backed by a reliable phylogenetic scheme, for which reason all European species in the ERMS context are maintained under genus Trivia, around the type species Trivia arctica.[1]
