Ciona intestinalis (Linnaeus, 1767)
IUCN

EOL Text
The Ciona intestinalis, and all tube tunicates, are thought to occupy a special evolutionary position because they contain a notochord and branchial basket, structures found mainly in chordates (Larousse 1967).

Often abundant and conspicuous in sheltered areas with some current, often on man-made structures, wrecks, buoys, ropes, etc. Also a component of moderately exposed rocky shallow sublittoral communities, but usually only as solitary individuals.

The vase tunicate has a thin, smooth, weak sac. It is also translucent. Nevertheless, the sac is very tough. These animals are eaten in countries surrounding the Mediterranean Sea. They cut open the sac and slurp the animal up. Be aware if you plan on eating one that it makes some people feel very miserable! They discover that they are allergic.

Ciona intestinalis feed mainly on fine detrital particles and phytoplankton (Coleman 1991). During the cirulation of water through the large gill basket, food particles are taken from the water and the endostyle secretes mucus to trap the food. It is then passed to the dorsal midline of the pharynx where it is rolled into a mucus rope and passed to the stomach. From here it passes to the intestine, and the faecal pellets formed go from the anus to the atrial opening where they are expelled from the body (Larousse 1967).

De doorschijnende zakpijp heeft een dunne, gladde, slappe mantel. Hij is ook doorschijnend. Toch is de mantel erg taai. In de landen om Middellandse zee worden ze wel rauw gegeten door mensen. Ze snijden de mantel open en slurpen het dier naar binnen. Als je dat wil proberen moet je wel weten, dat sommige mensen er erg beroerd van kunnen worden! Die zijn er allergisch voor.

Relatively short-lived and fast-growing but not seasonal in most habitats. Ciona populations show tremendous fluctuations of numbers over a period of years and may be very opportunistic, rapidly colonising new structures or areas cleared by abnormal fluctuation of temperature or salinity.

This species is a simple, solitary ascidian, with a thin outer covering or tunic. Overall shape is cylindrical, similar to a vase. The body measures 4-15 cm in length, and attaches to the substrate at its base. The oral and atrial siphons are positioned close together at the anterior end of the body. Overall, the tunic is smooth and translucent, lacking any pigment flecks. A diagnostic red spot at the end of the sperm duct is visible through the tunic.

Ciona intestinalis is a large solitary sea squirt which grows up to 15 cm in length. The body is soft, retractile and a pale translucent greenish/yellow, through which the internal organs are visible. Sometimes there are orange bars on the body. There are two openings or siphons which may have yellow margins with orange/red pigment spots.Also sometimes known as a sea vase.

The life span of most ascidians is about one year (Grzimek 1972). 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. The larva lasts about 36 hours, depending on the temperature of the area, after which it settles and metamorphoses into an adult (Coleman 1991).
