Question

Name the phylum whose members possess a notochord. Please explain what a notochord is. Thanks in advance!

Answer 1

The only phylum with Notochord is "Chordata"

Notochord is a rod-like structure, and it can be seen in human babies, but when they grow, it grows into back-bone. Notochord still found in Urochordata and Cephalochordata, but in higher vertebrates like humans, you'll find "Back bone" instead of a notochord.

Hope this helps!

Answer 2

Chordata
notochord is a mesodermally rod like structure which forms vertebral column in higher vertebrates
