Taxonomy51511 - Ciona savignyi

Genome assembly and annotationi GCA_000149265.1 from Ensembl

Ciona savignyi (the Pacific transparent sea squirt) is a solitary, sessile tunicate species. Native to shallow marine waters around Japan, it has also spread to the west coast of North America. Like the closely related species C. intestinalis, it is regarded as a pest species since it forms dense aggregates on man-made structures such as boat hulls and aquaculture rafts. It is of interest to researchers studying chordate development and evolution.

The genome, estimated to be 180 Mb in size, derives from a single individual from San Francisco Bay. The genome is highly polymorphic making assembly challenging.
