What are 5 types of vertebrates? The phylum chordata
Chordate
A chordate is an animal of the phylum Chordata. During some period of their life cycle, chordates possess a notochord, a dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail: these five anatomical features define this phylum. Chordates are also bilaterally symmetric; and ha…

What are the characteristics of reptiles?
Reptiles include tetrapods such as snakes, crocodiles, tuataras and turtles. The characteristic feature of reptiles is that they are ectothermic in nature . Snakes are still considered tetrapods though they have no visible limbs. This is due to the fact that snakes evolved from ancestors that had limbs.
What is the distinguishing feature of amphibians from reptiles?
The distinguishing feature that separates amphibians from reptiles is their breeding behaviour. Most amphibians need a body of water to breed as their eggs are shell-less.

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 Makes Something a Vertebrate?
A vertebrate is an animal from the kingdom Animalia. Specifically, it is an animal that has a backbone. The term vertebrate is derived from the Latin word vertebratus, which means joint of the spine. The vertebrae are the small bones that make up the spinal canal or backbone. Vertebrates make up approximately 3% of the known animal species. They are found on land, underground, and in the water.
What kingdom are vertebrates in?
Vertebrates are a group of animals found in Kingdom Animalia. They are in the Phylum Chordata. They are in the subphylum Vertebrata. There are seven classes within this subphylum. The classes of vertebrates include Agnatha (jawless fish), Chondrichthyes (cartilaginous fish), Osteichthyes (bony fish), Amphibia (amphibians), Reptilia (reptiles), Aves (birds), and Mammalia (mammals).
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.
