Reproduction Preferences Additional InformationAtrina fragilis is assumed to be long lived due to its large size and longevity is expected to be in excess of 10 years (D. Minchin, pers. comm.). Butler et al. (1993) report that the related Mediterranean genus Pinna nobilis may live up to 18 yr. Dispersion is assumed to be possible over large distances due to the pelagic life history. However, Butler et al. (1993) mention evidence for genetic population sub-division in Pinna bicolor within the Gulf of St Vincent in South Australia, which suggests that effective dispersal is lower than expected.
