Vertebrates

Definition of Vertebrates as it relates to Animals, Insects, Mammals, Gnathostomata

Vertebrates are a group of animals characterized by the presence of a notochord, which is a flexible, rod-like structure that runs along the length of the body during development, and eventually becomes part of the vertebral column in adults. This group includes animals such as fish, amphibians, reptiles, birds, and mammals. As a subgroup of Gnathostomata, all vertebrates possess jaws, which is a defining feature of this clade. Vertebrates are also characterized by the presence of a true brain, protected by the skull, as well as a complex nervous system. They also have a closed circulatory system, with a heart that pumps blood through a network of blood vessels. Vertebrates are unique among animals in that they have a specialized structure for respiration, called lungs. This allows them to extract oxygen from the air and release carbon dioxide, making it possible for them to live in environments where water is not readily available. Additionally, vertebrates have a wide range of reproductive strategies, including internal fertilization, laying eggs, and giving live birth. In summary, Vertebrates are animals that possess a notochord, jaws, a true brain, closed circulatory system, specialized respiratory structures (lungs) and various reproductive strategies which makes them unique in the animal kingdom. They fall under Gnathostomata, a group of animals characterized by the presence of jaws.
