A chordate ( / ˈkɔːrdeɪt / KOR-dayt) is a deuterostomic animal belonging to the phylum Chordata ( / kɔːrˈdeɪtə / 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.
Chordates, phylum Chordata, are a phylum of animals which have a notochord. The group includes vertebrates, with some closely related invertebrates.
The Cambrian chordates are an extinct group of animals belonging to the phylum Chordata that lived during the Cambrian, between 538 and 485 million years ago. The first Cambrian chordate known is Pikaia gracilens, a lancelet-like animal from the Burgess Shale in British Columbia, Canada.
This article contains a list of all of the classes and orders that are located in the Phylum Chordata.
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).
Evolution and paleontology. Many scientists maintain that chordates originated sometime earlier than 590 million years ago; that is, they predate the fossil record. Such early representatives were soft-bodied and therefore left a poor fossil record. The oldest known fossil chordate is Pikaia gracilens, a primitive cephalochordate dated to ...
The characteristic features of Chordata are a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. Chordata contains two clades of invertebrates: Urochordata (tunicates) and Cephalochordata (lancelets), together with the vertebrates in Vertebrata.
In chordates, four common features appear at some point during development: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. The endostyle is embedded in the floor of the pharynx.
Feb 28, 2021 · Identify the common characteristics of chordates. Vertebrates are members of the kingdom Animalia and the phylum Chordata. Recall that animals that possess bilateral symmetry can be divided into two groups—protostomes and deuterostomes—based on their patterns of embryonic development.
The characteristic features of Chordata are a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. Chordata contains two clades of invertebrates: Urochordata (tunicates) and Cephalochordata (lancelets), together with the vertebrates in Vertebrata.
chordate , Any member of the phylum Chordata, which includes the most highly evolved animals, the vertebrates, as well as the marine invertebrate cephalochordates (see amphioxus) and tunicates.
Chordate Medical Holding AB (publ) is a medical technology company that has developed, patented and CE-marked Ozilia® Migraine (formerly K.O.S), a neuromodulation and drug-free treatment technology for chronic migraine and chronic rhinitis.
The endostyle is an organ in the pharynx of chordate animals that assists in filter-feeding, and is found in adult cephalochordates and urochordates (sea squirts, salps and larvaceans), as well as in the larvae of some basal vertebrates (specifically the lampreys), but has been transformed through evolution into the thyroid in other vertebrates.
more testing Chordates ( / ˈkɔːrdeɪts /) are animals possessing a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail for at least some period of their life cycles.
Apr 7, 2019 · A chordate is an animal that belongs to the phylum Chordata, which is part of the Deuterostomes kingdom. Organisms in the Deuterostomes kingdom have a distinct characteristic: their anus develops before their mouth in early embryonic stages.
Apr 22, 2015 · The first step in unravelling chordate origins is the establishment of a robust deuterostome phylogeny ( Fig. 1 ). The chordates, uniting vertebrates, tunicates and cephalochordates, were first...

Chordata este o încrengătură de animale ce posedă coardă dorsală. Încrengătura include acraniatele, ciclostomatele, peștii, amfibienii, reptilele, păsările și mamiferele. Deși sunt foarte diverse, cordatele posedă caracteristici comune. Toate cordatele au schelet axial, intern.
Los cordados ( Chordata, del griego χορδωτά khordota ‘con cuerda’) son un filo del reino animal caracterizado por la presencia de una cuerda dorsal o notocorda (o notocordio) de células turgentes, 1 tubo neural hueco en posición dorsal, hendiduras branquiales y cola, por lo menos en alguna fase del desarrollo embrionario. 2 Se ...
Chordate genomics is the study of the evolution of the chordate clade based on a comparison of the genomes of several species within the clade. The field depends on whole genome data (the entire DNA sequence) of organisms.
Хордати ( лат. Chordata) су тип деутеростомних животиња. За најтипичније савремене представнике узимају се кичмењаци. Они поседују нотохорду, шупљу дорзалну нервну цев, фарингеалне тонзиле, ендостил, и постанални реп, током бар неког периода њиховог животног циклуса.
