Invertebrate vs. Vertebrate: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 7, 2024
Invertebrates lack a backbone or spinal column, while vertebrates possess a backbone and spinal column.

Key Differences

Invertebrates do not have a vertebral column (backbone), whereas vertebrates are characterized by their spinal column, a series of vertebrae extending from the skull to the tail.
