A chordate is an animal of the phylum Chordata. During some period of their life cycle, chordates possess a notochord, a dorsal nerve cord, pharyngeal slits, and a post-anal tail: these four anatomical features define this phylum. Chordates are also bilaterally symmetric, and have a coelom, metameric segmentation, and circulatory system. The Chordata and Ambulacraria together form the superphylum Deuterostomia. Chordates are divided into three subphyla: Vertebrata; Tunicata or Urochordata; and C

Filum Chordata adalah kelompok hewan, termasuk vertebrata dan beberapa binatang yang mirip invertebrata yang memiliki ciri-ciri yang serupa. Semua anggota kelompok ini, pada suatu saat dalam kehidupan mereka, memiliki notokorda, tali saraf dorsal berongga, celah faring (pharyngeal slits), endostyle, dan ekor berotot yang melewati anus.

From Wikipedia, the free encyclopedia Conodonts (Greek kōnos, " cone ", + odont, " tooth ") are extinct agnathan chordates resembling eels, classified in the class Conodonta. For many years, they were known only from tooth-like microfossils found in isolation and now called conodont elements. Knowledge about soft tissues remains limited.

This phylum is probably the most notable phylum, as all human beingsand other animals and birds that are known to you, fall under this phylum. The most distinguishing character that all animals belonging to this phylum have is the presence of notochord. Chordates show four features, at different stages in their life. They are: 1. Notochord– It is a longitudinal rod that is made of cartilage and runs between the nerve cord and the digestive tract. Its main function is to support the nerve cord. In Vertebrate animals, the vertebral column replaces the notochord. 2. Dorsal Nerve Cord – This is a bundle of nerve fibres which connects the brain to the musclesand other organs. 3. Post-analtail – This is an extension of the body beyond the anus. In some chordates, the tail has skeletal muscles, which help in locomotion. 4. Pharyngeal slits–They are the openings which connect the mouth and the throat. These openings allow the entry of water through the mouth, without entering the digestive...
They are bilaterally symmetrical and triploblastic.Chordates are coelomate and show an organ system level of organisation.They have the characteristic notochord, dorsal nerve cord, pharyngeal slits.Also, they have a post-analQ: Can chordates be found in a specific kind of habitat? Ans: We find Chordates in diverse habitats, including marine, freshwater and terrestrial habitats. Q: Which subphylum does Branchiostoma belong to? Ans: Cephalochordata Q: “All vertebrates are chordates but not all chordates are vertebrates.” Justify Ans: Vertebrata is a subphylum of Chordata. The vertebrates have a vertebral column, something like the notochord. Vertebrates show all the characteristic features of the phylum Chordata, such as the notochord, dorsal nerve cord, pharyngeal slits and post-anal tail. But the phylum Chordata also has other two subphyla, called the Urochordata and Cephalaochordata. These are invertebrate animals but show some distinguishing attributes of Chordates, like the presence of notochord. And hence, we can say that all vertebrates are chordates, but not all chordates are vertebrates.
