Answer 2

Answer:

A vertebrate is an animal that has all of the following characteristic features at some point in its life:

• A stiff rod running through the length of the animal (it could either be the vertebral column and/or notochord)
• Humans and all other vertebrates possess a notochord as an embryo and it eventually develops into the vertebral column.
• A bundle of nerves run above the vertebral column (spinal cord) and the alimentary canal exists below it.
• The mouth is present at the anterior portion of the animals or right below it.
• The alimentary canal ends in the anus, which opens to the exterior. The tail extends after the anus.

Example: Agnatha, Chondrichthyes, and Osteichthyes (all fishes); Amphibia (amphibians); Reptilia (reptiles); Aves (birds); and Mammalia (mammals).
