Question

what is post anal tail

Answer 1

All chordates have a post-anal tail. Apost-anal tail is an extension of the body that runs past the anal opening. In some species, like humans, this feature is only present during the embryonic stage. The chordata phylum is divided into three groups or subphylums: lancelets, tunicats, and vertebrates.
