vertebrates vs chordates
Chordates and vertebrates are two groups of higher animals. Both chordates chordstes vertebrates are deuterostomes. Vertebrates are a type of advanced chordates. Chordates are characterized by the presence of a notochord. Both chordates and vertebrates contain a nerve cord, pharyngeal gill slits, and post-anal tail at some points of their life. The main difference between chordates and vertebrates is that some chordates do vertebrates vs chordates have a vertebral column whereas all vertebrates have a vertebral column. In vertebrates, the vertebral column surrounds and protects the nerve cord. Both chordates and vertebrates consist of a central nervous the congressmans. The brain of the vertebrates is protected by the skull.
Main Difference – Chordates vs Vertebrates
What are Chordates — Definition, Classification, Characteristics 2. What are Vertebrates — Definition, Classification, Characteristics 3. Chordates refer to an animal phylum that contains a notochord, dorsal central nervous system, pharyngeal gill slits, and a post-anal tail.
Chordates are classified into three subphyla: Urochordata, Cephalochordata, and Vertebra. Urochordata contains sea squirts and salps that secrete a tunica to the outside of the body.

Cephalochordata contains lancelets. Vertebrata contains mammals, birds, reptiles, amphibians, and fish. The diversity of chordates is shown in figure 1. Chordates are deuterostomes with a bilateral body plan.
Related Access Points
They are also coelomates. The notochord of chordates is a stiff, cartilage rod, which extends along the body. The dorsal nerve tube connects with the peripheral nervous system and acts as the central nervous system. The pharyngeal gill slits occur just behind the mouth. They serve as a filter-feeding system in some chordates.
The post-anal tail is a muscular tail and extends behind the anus. Vertebrates refer to a large group of animals which consist of a backbone, surrounding the nerve cord.]
