(15) Corella eumyota Traustedt, 1882

Status in U.K. – non-native.

The “orange tipped sea squirt” Corella eumyota has been recorded at many monitoring programme sites, each year since 2014, from scrape, settlement panel and rapid assessment samples. Within Scapa Flow, it has been recorded at The Grinds and Gutter Sound navigational buoys and from mooring buoys in Ore Bay; it has also been recorded from all three marinas in the Orkney Islands: Stromness, Kirkwall and Westray.

The first U.K. record was from 2004 on the south coast of England, at Brighton Marina, Gosport Marina and Weymouth Harbour (Arenas et al. 2006). It was first recorded in Scotland in 2009, on the west coast and its first record in Orkney was in 2012 (Nall et al. 2015). More recently, Want et al. (2017) provided records from Orkney from renewable energy infrastructure.
