A chordate (/ ˈ k ɔːr d eɪ t / KOR-dayt) is a deuterostomal bilaterian animal belonging to the phylum Chordata (/ k ɔːr ˈ d eɪ t ə / kor-DAY-tə). All chordates possess, at some point during their larval or adult stages, five distinctive physical characteristics (synapomorphies) that distinguish them from other taxa.

Phylum Chordata is classified into three subphyla, namely. Vertebrata (vertebrates). The subphylum Urochordata and Cephalochordata are collectively known as protochordates, which are marine animals. They are invertebrates but they share attributes of chordates. The adults are fixed to the substratum.

2024年10月2日 · Phylum Chordata includes a diverse group of animals, categorized into three main subphyla: Urochordata, Cephalochordata, and Vertebrata. Below are examples of species within each subphylum: Subphylum Urochordata (Tunicata): These are marine animals, typically characterized by their sac-like bodies and a tunic made of a cellulose-like substance.

This article contains a list of all of the classes and orders that are located in the Phylum Chordata. The subphyla Tunicata and Vertebrata are in the unranked Olfactores clade, while the subphylum Cephalochordata is not.

2024年12月20日 · 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.

2014年11月7日 · Traditional metazoan phylogeny classifies the Vertebrata as a subphylum of the phylum Chordata, together with two other subphyla, the Urochordata (Tunicata) and the Cephalochordata. The Chordata, together with the phyla Echinodermata and Hemichordata, comprise a major group, the Deuterostomia.

Traditional metazoan phylogeny classifies the Vertebrata as a subphylum of the phylum Chordata, together with two other subphyla, the Urochordata (Tunicata) and the Cephalochordata. The Chordata, together with the phyla Echinodermata and …

2019年4月7日 · There are three subphyla to Chordata: Cepahlochordata, Urochordata, and Vertebrata. Chordates generally have bilaterally symmetric bodies, though a few exceptions exist, and they share distinct characteristics that will be discussed later on. Chordates have all of these characteristics, at least at some point in their lives.

2017年1月18日 · We divide Phylum Chordata into three subphylums: Maintain all four key characteristics throughout all life stages. The pharynx has ~100 pharyngeal slits which are used in feeding (filter food particles out of the water). Primitive or simple -> similar to chordate ancestors that gave rise to vertebrates.

2022年8月24日 · Urochordata often occur in colonial form as adults as seen below. The subphylum Cephalochordata (lancelets) exhibit all the traits of Chordata as adults. Like Urochordata, they are also marine organisms and may be found world wide in shallow waters.
