Images of species taken widely across the south Devon and Cornwall coast, and at various times of the year.

As seen here there is great variation in the colour of this species. On finding it, it is worth checking for the prescence of sea slugs and flatworms that are known to feed on it. They may be difficult to see as they are often well camoflaged.

Scientific and European Names:
Botryllus schlosseri, Star ascidian, Golden star tunicate, Star squirt, Gesterde Geleikorst, Paarse Geleikorst, Botrylle etoile, Stern-Seescheide.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help

people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
