(7) Boccardia proboscidea Hartman, 1940

Status in U.K. – non-native.

One record of the burrowing worm Boccardia proboscidea was made from the monitoring programme, from Scapa Pier, in 2014.

Boccardia proboscidea has recently become recognised as a global invader (Simon et al. 2010; Kerckhof and Faasse 2014; Jaubet et al. 2015; Spilmont et al. 2018). There are unpublished records from throughout Britain and Ireland and a published record from Skye (Hatton and Pearce 2013), suggesting that the species has long been established in British waters. The record presented here from 2014 is the first from Orkney.
