Invasion

Invasion Description

1st Record: HMAS 'Anzac', moored at Garden Island/Western Australia/Indian Ocean (4/2011, McDonald 2012, a single mussel)

There is no evidence of establishment of P, viridis, although hundreds of fouled vessels have probably visited northern Australia up to 2019. Bayesian analysis suggests that P. viridis cannot be considered a high-risk invader (Heersink et al. 2019).
