What is the difference between vertebrates and chordates?
Vertebrates:
Vertebrates are animals that have a backbone or vertebral column.
Chordates:
They are distinguished essentially by the existence of a notochord, a dorsal hollow nerve cord, and paired pharyngeal gill slits.
Difference between vertebrates and chordates:
Vertebrates | Chordates |
1. Vertebrates are a wide category of creatures that have a backbone. | 1. Chordates are animals that have a notochord and a dorsally located hollow nerve cord. |
2. They are made up of advanced chordates. | 2. They are made up of both primitive and sophisticated chordates. |
3. In vertebrates, notochord is only present during embryonic stages. | 3. In lower chordates, notochord is persistent throughout the life. |
4. They have a cartilaginous or bony skeleton and a vertebral column that surrounds the nerve cord. | 4. Invertebrate chordates lack a vertebral column and a cartilaginous or bony skeleton. |
5. Vertebrates have limbs or fins. | 5. Chordate invertebrates lack limbs. |
6. Vertebrates have jaws. | 6. Jaws are absent in chordates (invertebrates). |
7. All vertebrates are chordates. | 7. All chordates are not vertebrates. |
