Chordates are animals with backbones. Animal groups in the chordate phylum include fish, amphibians, reptiles, birds and mammals.
Animals with backbones are the most highly evolved groups of animals, the most complex and complicated. They have interior skeletons and have bilateral symmetry. They have more advanced brains.
An chordate has an inner skeleton with a backbone. It generally has four appendages that are in the forms of legs, arms, wings or fins.
|Digestion||An chordate takes in food through the mouth. The chordate has a mouth with a tongue. Some have teeth and some do not. It has a digestive system with stomach, intestines. Chordates eat plants and animals.|

|Respiration||A chordate takes in oxygen and gets rid of carbon dioxide through lungs or gills.|
|Reproduction||A chordate reproduces sexually.|
