With rare exceptions, tunicates are hermaphrodites, but reproduction may be by sexual or asexual (budding) means. No, they do not. They are invertebrate members of the pylum Chordata. Like other chordates, they have a dorsal nerve cord and a notochord.

Based on molecular analysis, vertebrates appear to be more closely related to lancelets (cephalochordates) than to tunicates (urochordates) among the invertebrate chordates. This evidence suggests that the cephalochordates diverged from Urochordata and the vertebrates subsequently diverged from the cephalochordates. 2012-07-18 Chordata - Vertebrates, Tunicates, Lancelets At some point, all of the organisms in this phylum have a structure called a notochord.A notochord is a flexible rod-like cord of cells that provides the main support for the organism's body during its embryonic stage.

Tunicate, Urochordata, Vertebral Column, Vertebrata, Vertebrate, Vertebrates Animals in the phylum Chordata share five key chacteristics that appear at 5 Sep 2008 2003) because the tunicates and vertebrates are a sister group loss in the tunicate genome, as protostomes and vertebrates share clear 19 Jun 2008 The tunicates C. intestinalis and Oikopleura dioica, however, share many fewer introns with vertebrates or amphioxus. Notably, intron presence or Tunicates or urochordates (appendicularians, salps and sea squirts), cephalochordates (lancelets) and vertebrates (including lamprey and hagfish) constitute Although all three share a common (probably Cambrian) ancestor, cephalochordates like the lancelets (AKA, “Amphioxus”) apparently diverged from that common Most species within the phylum Chordata are vertebrates, or animals with backbones (subphylum However, we share this phylum with two groups of invertebrates as well. Tunicates (subphylum Urochordata) and lancelets ( subphylum Chordates are eucoelomate deuterostomes, and probably share a common of vertebrate origins suggests that vertebrates arose from tunicate larvae by a 23 Feb 2021 Several zooids may share a single, common cloacal aperture, but each transmission of parasitic infections to humans and other vertebrates.

Most tunicates live a sessile existence on the ocean floor and are suspension feeders . However, chains of thaliacean tunicates called salps (Figure 3) can swim actively while feeding, propelling themselves as they move water through the pharyngeal slits. Tunicates or urochordates (appendicularians, salps and sea squirts), cephalochordates (lancelets) and vertebrates (including lamprey and hagfish) constitute the three extant groups of chordate animals.

Vertebrates display the four characteristic features of the chordates; however, members of this group also share derived characteristics that distinguish them from invertebrate chordates. Vertebrata is named for the vertebral column , composed of vertebrae, a series of separate bones joined together as a backbone (Figure 6).
