Alien species alert

​New Cooperative Research Report (CRR) focusses on Didemnum vexillum Kott (2002), a high-impact, invasive sea squirt species native to Japan.
Published: 7 March 2017

The sea squirt D. vexillum is generally a temperate cold-water organism, and its introduced range currently includes New Zealand, the Netherlands, France, Ireland, United Kingdom, Spain, Italy, and both the west and east coasts of the United States and Canada.

Like other invasive sea squirts, D. vexillum has the capacity to reproduce rapidly, outcompete native species, deteriorate environmental integrity, and cause significant economic harm.

This CRR aims to increase awareness of this species, with a focus on identification, natural history, current global distribution, potential impacts, and prospects for management and control where introductions occur.
