Austrominius modestus - CABI

Austrominius modestus is native to New Zealand, where it is very common in harbours and estuaries, on a range of substrates, in the midlittoral and shallow subtidal ( Moore, 1944; Morton and Miller, 1968; Foster, 1978 ). According to Foster (1982) it is the commonest fouling barnacle in New Zealand harbours.
