The New Zealand sea star is biologically very similar to the Derwent River sea star, and consequently it is believed that the native species may have been genetically swamped by the invader.

Patiriella exigua is morphologically distinct in both its adult and larval morphologies. (1867). The gametes of P. calcar and P. gunnii were reciprocally compatible: laboratory crosses between these species produced viable hybrid juveniles. These findings remove doubt about the validity of the species; the recorded habitat and restricted range of Patiriella littoralis are not exceptional for an asterinid seastar.
