A vertebrate is an animal that has all of the following characteristic features at some point in its life:
- A stiff rod running through the length of the animal (it could either be the vertebral column and/or notochord)
- Humans and all other vertebrates possess a notochord as an embryo and it eventually develops into the vertebral column.
- A bundle of nerves run above the vertebral column (spinal cord) and the alimentary canal exists below it.

How big are sharks?
In size, sharks range from the whale shark, nearly 10 metres in length, to rather small species, three centimetres in length. They usually weigh 25 to 200 kilograms (55 to 440 pounds). Sharks are predatory animals. Some large shark species (basking and whale sharks) filter feed on small crustaceans. Herbivorous sharks are unknown. Sharks swim by undulations of the tail, but rays “fly” through the water by undulations of the pectoral fins. Most species occur in near-shore waters, but some range widely throughout the oceans. A few are found in deep water.
What are the features of vertebrates?
Vertebrates have several basic features. First, vertebrates have a complex central nervous system. This includes a well-developed brain and a spinal cord that is held in the vertebral column. Vertebrates also have a closed circulatory system. This means the blood of a vertebrate circulates through its body in blood vessels. Vertebrates also have skin that is protected by hair, feathers, or scales. Finally, as embryos, vertebrates have neural crest cells. These cells develop into nerve cells and cells that form facial features.

What are the roles of vertebrates in an ecosystem?
Vertebrates take on several key roles in an ecosystem. Many predator species in ecosystems are large vertebrates. Examples of predatory vertebrates include lions, eagles, and sharks. Many prey species in ecosystems are vertebrates as well. These include animals such as mice, rabbits, and frogs. Many vertebrates take on the role of scavengers in ecosystems. They are important because they rid the habitat of dead animals. For example, turkey vultures and hyenas are both vertebrate scavengers. Additionally, many vertebrates take on the role of pollinators in ecosystems. For example, bats and monkeys may aid in the spread of pollen as they visit various trees and plants.
Why are vertebrates important to humans?
Vertebrates are also important to humans for a variety of reasons. Humans use vertebrates as domesticated animals . These animals can provide milk, food, and clothing. They can also aid in work. Agricultural animals are typically vertebrate animals. Humans also hunt many wild vertebrate animals, using them as a food source.

A vertebrate's central nervous system is composed of a well-developed brain, found in the skull, and a spinal cord encased by the vertebral column.
Do vertebrates have a circulatory system?
Vertebrates have both axial and appendicular skeletons that combine to make a highly developed internal skeleton. They possess a closed circulatory system, meaning that their blood always flows in blood vessels, and their respiratory system is located close to the throat.

Why are reptiles cold blooded?
Cold blood. Reptiles, for example, have a variable body temperature depending on the environment where they are found. For this reason (and together with amphibians) they are said to be cold- blooded animals . In the case of fish their body temperature is also variable. For this reason there are cold water and other tropical (warm) water fish.

What Are Vertebrates like?
- Vertebrates are the living beings that have a more evolved organism. Vertebrates are advantaged over the other creatures because they own great adaptations to the environment. The group of vertebrates is ahomogeneous set of animals with common anatomical characteristics. Hence, all vertebrates have a certain similarity in their basic structure.
Vertebrate Skeleton
- Not all vertebrates have vertebrae, as in the case of agnathans (lampreys). The vertebrate notochord (a structure originating from the mesoderm and which has the function of guiding the neural tube during the development of the nervous system) is replaced by the vertebral column. The inner skeleton can be made of bone tissue or cartilaginous tissue(like sharks). Vertebrates …
Types of Vertebrates
- The vertebrate group consist of large species. There are far fewer vertebrates than invertebrates(fewer than 50,000 species versus 1 million, respectively) due in part to the larger size of vertebrates. Vertebrates are classified into 5 groups or classes: fish, amphibians, reptiles, birds, and mammals. Each group is characterized by a specific anatomy and a particular way of …
