Aplousobranchia
Aplousobranchia is an order of sea squirts in the class Ascidiacea, first described by Fernando Lahille in 1886. They are colonial animals, and are distinguished from other sea squirts by the presence of relatively simple pharyngeal baskets. This provides the etymology of their name: in Ancient Greek, () means "simple". The posterior part of the abdomen contains the heart and gonads, and is typically larger than in other sea squirts.

Ascidiacea
Ascidiacea, commonly known as the ascidians or sea squirts, is a paraphyletic class in the subphylum Tunicata of sac-like marine invertebrate filter feeders. Ascidians are characterized by a tough outer test or "tunic" made of the polysaccharide cellulose. Ascidians are found all over the world, usually in shallow water with salinities over 2.5%. While members of the Thaliacea (salps, doliolids and pyrosomes) and Appendicularia (larvaceans) swim freely like plankton, sea squirts are sessile animals after their larval phase: they then remain firmly attached to their substratum, such as rocks and shells. There are 2,300 species of ascidians and three main types: solitary ascidians, social ascidians that form clumped communities by attaching at their bases, and compound ascidians that consist of many small individuals (each individual is called a zooid) forming large colonies. Sea squirts feed by taking in water through a tube, the oral siphon. The water enters the mouth and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Didemnidae
Didemnidae is the largest family of colonial tunicates in the order Aplousobranchia. These marine animals are found in shallow water on the seabed. Members of this family have reduced zooids that form highly integrated and encrusting sheet-like colonies. The body of each zooid is divided into a thorax and an abdomen. They are highly speciose with 578 named species representing a fifth of the species in the class Ascidiacea and members of this family can be found in marine waters across the globe. Didemnidae is the only genera within Chordata to form obligate photo symbiotic relationships which are made with cyanobacteria form the genus Prochloron.

Tunicate
Tunicates are marine invertebrates belonging to the subphylum Tunicata ( ). This grouping is part of the Chordata, a phylum which includes all animals with dorsal nerve cords and notochords (including vertebrates). The subphylum was at one time called Urochordata, and the term urochordates is still sometimes used for these animals. Despite their simple appearance and very different adult form, their close relationship to the vertebrates is certain. Both groups are chordates, as evidenced by the fact that during their mobile larval stage, tunicates possess a notochord, a hollow dorsal nerve cord, pharyngeal slits, post-anal tail, and an endostyle. They resemble a tadpole. Tunicates are the only chordates that have lost their Myomere, myomeric segmentation, with the possible exception of the seriation of the gill slits. However, Doliolida, doliolids still display segmentation of the muscle bands. Some tunicates live as solitary individuals, but others replicate by budding and be ...

Genera , WoRMS recognizes the following genera in the family Clavelinidae: * ''Clavelina'' * ''Euclavella'' * ''Nephtheis'' * ''Pycnoclavella'' Phylogeny ''Pycnoclavella'' has occasionally been placed in a separate family, Pycnoclavellidae, although Phylogeny, phylogenetic studies have recovered it as a relative of ''Clavelina''.

Didemnum
''Didemnum'' is a genus of colonial tunicates in the family Didemnidae. It is the most speciose genus in the didemnid family. Species in this genus often have small calcareous spicules embedded in the tunic and form irregular or lobed colonies. Some ''Didemnum'' species, including '' Didemnum vexillum'' and '' Didemnum perlucidem'' are considered invasive species. In early 2006, ''Didemnum vexillum'' was found covering a 230 km2 area of cobble habitat in Georges Bank off the coast of New England, and is classified as an invasive species of greatest concern in coastal areas throughout Europe, New Zealand, and North America. ''Didemnum'' sp. invasions have also been recorded in Canada, the Mediterranean, and the Netherlands. Species in this genus can be found in tropical or temperate regions. Some tropical species such as ''Didemnum molle'' have photosynthetic algae in their tunics. Species The following species are recognised in the genus ''Didemnum'': *'' Didemnum abradatu ...
