Trochida is an order of small to very large vetigastropod, Recent and extinct sea snails with gills and an operculum.[2]
Still existing trochomorphs stem from a large, archaic clade.[3] According to Uribe et al. (2016) the superfamilies Angarioidea and Phasianelloidea are deeply nested within the superfamily Trochoidea sensu Williams (2012).[4][5] The revised taxonomy (2017) of Bouchet et al. therefore only recognizes the superfamily Trochoidea (including Angarioidea and Phasianelloidea).
