Status in U.K. – cryptogenic.

Ascidiella scabra has been recorded from many monitoring programme sites, each year since 2012, from scrape, settlement panel and rapid assessment samples.

Genetic studies ( Nishikawa et al. 2014) have confirmed the distinction between this species and A. aspersa , to which it is very similar and the two species share the same type locality. It is likewise considered invasive in Japan but has been listed as cryptogenic in the Mediterranean ( López-Legentil and Legentil 2015). It should be considered cryptogenic in British waters until its origin has been determined.
