The vertebrates make up the subphylum Vertebrata with some 65,000 species, by far the largest grouping in the phylum Chordata. The vertebrates include mammals, birds, amphibians, and various classes of fish and reptiles. The fish include the jawless Agnatha, and the jawed Gnathostomata.

2018年12月26日 · The present zoological taxonomy classifies Vertebrata as a subphylum of the phylum Chordata, together with two other invertebrate subphyla, Cephalochordata (lancelets) and Urochordata (ascidians). The aim of this review is to discuss whether the subphylum Vertebrata is supported by data obtained from recent zoological research.

All the vertebrates or craniates are placed under the Subphylum Vertebrata or Craniata. In addition to the basic chordate fea­tures, the vertebrates possess many specialised characteristics that distinguish them from the invertebrate chordates and non-chordates. The main difference lies in the position of the nerve cord (Fig. 4.1).

2024年11月23日 · As chordates, all vertebrates have a similar anatomy and morphology with the same qualifying characteristics: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. However, the subphylum Vertebrata is distinguished from the phylum Chordata by the development of the notochord into a bony backbone.

Dalam sistem klasifikasi, vertebrata merupakan subfilum dari filum Chordata. Filum Chordata terdiri dari tiga subfilum, yaitu Urochordata, Cephalochordata, dan vertebrata. Simak lebih lengkap tentang penjelasan vertebrata berikut ini Grameds!

The majority of chordates belong to the subphylum Vertebrata, a group which, as its name suggests, is characterized by the possession of a metameric series of small skeletal structures, the vertebrae. These are associated with the notochord during embryonic development but in most cases replace it in adults.

Vertebrates comprise all species of animals within the subphylum Vertebrata (chordates with backbones), including all mammals, birds, reptiles, amphibians, and fish. Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described.

2025年1月17日 · Chordata terbagi menjadi empat subfilum: Vertebrata, Urochordata, Cephalochordata, dan Hemichordata. Namun, sub filum Urochordata dan Cephalochordata tergolong Invertebrata. Pada bagian tulang belakang hewan vertebrata berasal dari perkembangan notokord atau penyokong tubuh primer.

2020年2月16日 · Welcome to the subphylum Vertebrata. Most chordates are vertebrates and the subphylum itself comprises over 50,000 species of animals. Vertebrates are the animals most people think of when they think of the word ‘animal’. Fish, Amphibians, Reptiles, Birds and Mammals are all vertebrates.

The distinctive features of the subphylum Vertebrata are the vertebral columns in place of the notochord. The central nervous system of vertebrates is properly distinguished into the brain and spinal cord. Other unique features include the hepatic portal system and chambered hearts. Subphylum Vertebrata is divided into Agnatha and Gnathostomata.
