Comparative 3D‐anatomy of Appendicularian Endostyles (Tunicata, Chordata) ‐ A Tale of Reduction

Journal of morphology
Appendicularia comprises about 70 holoplanktonic species traditionally classified in three families: Oikopleuridae, Fritillariidae, Kowalevskiidae. Despite their eminent phylogenetic position and their important role in ocean ecosystems, most research ...

Phylum Chordata

2022
This chapter details the characteristics of the phylum Chordata. Unlike its subphylum Vertebrata, Chordata features the subphyla Cephalochordata and Urochordata as two subphylums whose members exist without backbones. Modern phylogenomic research shows that Urochordata is the sister group to Vertebrata, a clade known as Olfactores.

Encounters with the rare genus Helicosalpa (Chordata, Thaliacea, Salpida), using citizen science data

, 2020
Species within the genus Helicosalpa are pelagic tunicates with keg-shaped solitary zooids and aggregate zooids in chains (not whorls). They are also among the most rarely collected salps, with most observations from subtropical and tropical regions ...

Chordata: Appendicularia

2017
This chapter describes the taxonomy of Appendicularians (larvaceans), small free-swimming pelagic zooplankton. They belong to the phylum Chordata, which includes the vertebrates. Like other tunicates Appendicularia are relatively primitive forms compared to the vertebrates, although they exhibit three features that are common to all chordates at some ...
