Explain the "Phylum Chordata"
Answers
Answer:
The phylum chordata is named for the notochord, a longitudinal, flexible rod between the digestive tube and the nerve cord; in vertebrates, this is the spinal column. The chordates are also characterized by a dorsal nerve cord, which splits into the brain and spinal cord
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 belonging or pertaining to the phylum Chordata, comprising animals having a notochord, as the lancelets and tunicates, as well as all the true vertebrates, including fish, amphibians, reptiles, birds, and mammals.
