The biology of pelagic tunicates /
, 1998 Pelagic Tunicates play an important role in the sea as filter feeding animals of the macroplankton in geochemical cycling. This is the first book in fifty years to provide a full account of all the Tunicate groups.

Ancient origins: complement in invertebrates
Invertebrate Survival Journal, 2005 Proteins with obvious similarities to mammalian complement are widely distributed in the animal kingdom. In the vertebrate lineage, deuterostomes like sea urchins and tunicates express proteins that are homologues of C3, the central component of the ...

, 2006 Tunicates are marine animals close to vertebrates, and have the ability, unique among chordates, to form large colonies of clonal individuals. Among tunicates, the most frequently studied ascidians represent an ideal model for investigating aspects of ...

Widespread use of the "ascidian" mitochondrial genetic code in tunicates.
, 2020 Background: Ascidians, a tunicate class, use a mitochondrial genetic code that is distinct from vertebrates and other invertebrates. Though it has been used to translate the coding sequences from other tunicate species on a case-by-case basis, it is has ...

Matrix metalloproteinase Nas15 regulates the lumen formation and expansion in Ciona notochord
Frontiers in Ecology and EvolutionLumen formation, as a key process of biological tube construction, is essential in various physiological processes such as nutrient and waste transporting, gas exchanging, and structural supporting.

Appendicularians: Tiny Tunicates, Powerful Ocean Filters
Appendicularians are tiny planktonic tunicates, usually 2–8 mm long, that feed by beating their tail inside a transparent mucus “house.” This movement pumps seawater through external filters, traps very small food particles on internal filters, directs ...

Evolutionary mitogenomics of Chordata: the strange case of ascidians and vertebrates [PDF]
Invertebrate Survival Journal, 2009 The availability of almost one thousand complete mitochondrial genome (mtDNA) sequences of chordates provides an almost unique opportunity to analyse the evolution of this genome in the phylum Chordata, and to identify possible divergent evolutionary ...
