Question

five important features of sub phylum Cephalochordata​

Answer 1

Explanation:

Cephalochordata. Members of Cephalochordata possess a notochord, dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail in the adult stage. They do not have a true brain, but the notochord extends into the head, which gives the subphylum its name ( “cephalo” is Greek for head).
