Trochida Explained

Trochida is an order of small to very large vetigastropods. It includes recent and extinct sea snails with gills and an operculum.^[1]

Taxonomy

Extant trochomorphs stem from a large, archaic clade.^[2] According to Uribe et al. (2016) the superfamilies Angarioidea and Phasianelloidea are deeply nested within the superfamily Trochoidea sensu Williams (2012).^{[3] [4]} The revised taxonomy (2017) of Bouchet et al. therefore only recognizes the superfamily Trochoidea (including Angarioidea and Phasianelloidea).

Superfamilies

• Trochoidea Rafinesque, 1815

Synonyms:

• Angarioidea Gray, 1857: synonym of Trochoidea Rafinesque, 1815
• Phasianelloidea Swainson, 1840: synonym of Trochoidea Rafinesque, 1815
