Mar 29, 2024 · chordate, any member of the phylum Chordata, which includes the vertebrates (subphylum Vertebrata), the most highly evolved animals, as well as two other subphyla—the tunicates (subphylum Tunicata) and cephalochordates (subphylum Cephalochordata). Some classifications also include the phylum Hemichordata with the chordates.
All chordates are based on a bilateral body plan. [11] All chordates are coelomates, and have a fluid-filled body cavity called a coelom with a complete lining called peritoneum derived from mesoderm (see Brusca and Brusca). [12] 1 = bulge in spinal cord ("brain") 2 = notochord. 3 = dorsal nerve cord. 4 = post-anal tail.

Dec 15, 2021 · The most conspicuous and familiar members of Chordata are vertebrates, but this phylum also includes two groups of invertebrate chordates. Figure \(\PageIndex{1}\): All chordates are deuterostomes possessing a notochord.
Classification of Chordates. Living species of chordates are classified into three major subphyla: Vertebrata, Urochordata, and Cephalochordata. Vertebrates are all chordates that have a backbone. The other two subphyla are invertebrate chordates that lack a backbone.
However, not all chordates are vertebrates. All chordates have the following features at some point in their life (in the case of humans and many other vertebrates, these features may only be present in the embryo): pharyngeal slits - a series of openings that connect the inside of the throat to the outside of the "neck".
Hank introduces us to ourselves by taking us on a journey through the fascinatingly diverse phyla known as chordata. And the next time someone asks you who you are, you can give them the facts: you're a mammalian amniotic tetrapodal sarcopterygian osteichthyen gnathostomal vertebrate cranial chordate.
