New report of the Antarctic ascidian Corella eumyota (Tunicata: Ascidiacea) on the Galician coast (north-west Spain)

The first record of the non-indigenous Corella eumyota on the Galicia coast (north-west Spain) is reported. One hundred and forty-one specimens of this solitary ascidian were found on soft bottoms at 12 m depth in the inner part of the Ria de Vigo. This is a species from cooler waters of the southern hemisphere and was recorded for the first time in the northern hemisphere in 2002, in France. The specimens have been compared with Antarctic and South American museum samples. Some intraspecific variability was noted.
