vertebrates

Vertebrates are animals that have a backbone or spine, which provides support and protection for their nerve cord. This group includes mammals, birds, reptiles, amphibians, and fish. Vertebrates typically have a well-developed skeleton, complex organ systems, and specialized body parts like limbs or fins. They range from small creatures like frogs to large animals like whales. The backbone is a key feature, enabling these animals to move efficiently and develop diverse adaptations for survival. Overall, vertebrates are a broad and varied group distinguished by their internal skeleton and spinal column.
