Hi! Vertebrates are a subgroup of chordates that possess distinct characteristics, setting them apart from other chordates. In 120 words, I will outline the key features that distinguish vertebrates from other chordates:

1. Vertebral column: Vertebrates have a segmented backbone made of individual vertebrae, which surrounds and protects the spinal cord.

2. Endoskeleton: Vertebrates possess an internal skeleton made of bone or cartilage, providing structural support and allowing for movement.

3. Cranium: Vertebrates have a well-developed, bony or cartilaginous skull that encloses and protects the brain.

4. Complex organ systems: Vertebrates have more advanced organ systems, including a closed circulatory system with a multi-chambered heart, specialized respiratory organs (e.g., lungs or gills), and a centralized nervous system.

These key features differentiate vertebrates from other chordates, such as tunicates and lancelets, which lack these complex structures.
