Ciona Ciona is a genus of sea squirts in the family Cionidae 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
- Ecological Review of the Ciona Species Complex | The Biological . . .
We completed a comprehensive review of the ecology of Ciona spp to establish the similarities and differences between the widely distributed Ciona robusta and C intestinalis (and what little is known of the two other species, Ciona sp C and Ciona sp D)
- The Development and Growth of Ciona | Journal of the Marine Biological . . .
Artificial fertilization is readily accomplished, and at almost any time of the year, since Ciona is sexually mature above a certain size and reproduction is seasonal only to the extent of the rhythm of the growth cycle
- CIONA - Zoologyverse | 2025
Ciona is a genus of sea squirts, marine invertebrates belonging to the subphylum Tunicata (Urochordata) within the phylum Chordata Often called “sea vase” due to their vase-like appearance, species in this genus are sessile filter feeders, thriving in marine environments around the world
- Ciona intestinalis - Smithsonian Institution
Ciona intestinalis was formerly regarded as a species widely distributed in the North Pacific and Atlantic, probably introduced in the Northeast Pacific, and the Southern Hemisphere, and was considered native or cryptogenic on the coasts of the North (Van Name 1945)
- Ciona Genetics - PMC
Ascidians, such as Ciona, are invertebrate chordates with simple embryonic body plans and small, relatively non-redundant genomes Ciona genetics is in its infancy compared to many other model systems, but it provides a powerful method for studying
- ADW: Ciona intestinalis: INFORMATION
The Ciona intestinalis is hermaphroditic and releases sperm and eggs through the exhalent siphon Fertilization occurs at sea, and a tadpole-like larva is formed about 25 hours later
- Home - Ciona intestinalis v2. 0
The Ciona intestinalis genome is the smallest of any experimentally manipulable chordate This organism provides a good system for exploring the evolutionary origins of the chordate lineage, from which all vertebrates sprouted
