Answer 2

Answer:

• Vertebrates are animals with a backbone, also known as a spinal column.
• They make up most of the phylum Chordata, one among 38 animal phyla.
• A couple members of phylum Chordata, lancelets and tunicates, are invertebrates.
• Lancelets just have a notochord rather than a true spinal coumn, and tunicates only have a notochord during early development.
• Fish, sharks, rays, amphibians, reptiles, birds, and mammals (including humans) are vertebrates.
