What is the largest subphylum of Chordates?

Answer 1

The largest subphylum of chordates is the vertebrates. It currently includes 66,000 species.

All animals with gills, a central nervous system, and a backbone that have undergone at least one developmental stage are classified as vertebrates.

Along with jawless, bony, shark, and ray fish, they also comprise amphibians, reptiles, mammals, and birds.

All vertebrates have the same basic chordate body plan, which consists of a spinal cord (a tube of nerve tissue) running the length of the animal and the gastrointestinal tract below it.
