Ciona edwardsi | |
Ciona is a genus of Cionidae sea squirts.
The body of Ciona is bag-like and covered by a tunic, which is a secretion of the epidermal cells. The body is attached at a permanent base located at the posterior part, and the opposite bears two openings, the buccal (oral) and atrial (cloacal) siphons. The water is drawn into the ascidian through the buccal siphon and leaves the atrium through the atrial siphon.
Genome projects
As of 2008, the genomes of Ciona intestinalis and Ciona savignyi have been sequenced.
