<speciesfyi-glossary slug="vertebrate"></speciesfyi-glossary>Definition
An animal possessing a backbone or spinal column, including fish, amphibians, reptiles, birds, and mammals.
Detailed Explanation
Vertebrates represent a tiny fraction of animal species — roughly 65,000 species out of 8 million — yet they dominate ecological roles as large predators and herbivores. The vertebral column allows complex locomotion and houses the spinal cord. Vertebrates share a neural crest, a unique embryonic cell population that generates diverse structures including bones of the skull and peripheral nervous system.
