vertebrate
[ˈvɜːrtəbrɪt ]
Definition
animal biology
A vertebrate is an animal that possesses a backbone or spinal column. This classification includes a wide range of species from fish and amphibians to reptiles, birds, and mammals. Vertebrates are characterized by their complex skeletal structures that support the body and protect vital organs. They typically have a nervous system that is more complex than that of invertebrates, allowing for better movement and response to stimuli.
Synonyms
backboned animal, chordate.
Examples of usage
- The vertebrate class includes all mammals.
- Fish are one of the most diverse groups of vertebrates.
- Birds, as vertebrates, have a unique skeletal structure for flight.

Origin of 'vertebrate'
Main points about word origin
- The term comes from the Latin word 'vertere,' meaning 'to turn' or 'to change,' relating to the vertebral column's role in body movement.
- The suffix '-brate' is derived from 'bratus,' meaning 'having a certain structure,' referring to the backbone's importance.
The term 'vertebrate' derives from the Latin word 'vertebratus', which means 'jointed' or 'having joints'. It refers to the successive vertebrae that form the backbone of these organisms. The use of the term in English dates back to the early 19th century, reflecting the rising interest in biological classification and the study of anatomy during this period. This classification plays a crucial role in understanding evolutionary relationships among various species. Historically, vertebrates have been of great interest due to their complexity and diversity, influencing both scientific study and public fascination.
