Parvulastra is a genus of starfish belonging to the family Asterinidae.[2][3] The species of this genus are found in Southern Hemisphere.[1][3]

The genus shows an unusual reproductive mode within Asterinidae: Parvulastra parvivipara and Parvulastra vivipara are viviparous. Prior to their description as distinct species, they were considered variants of Parvulastra exigua, which has free-living (but non-feeding) larvae.[4]
