Chordates form a phylum of animals that are defined by having at some stage in their lives all of the following anatomical features: • A notochord, a stiff rod of cartilage that extends along the inside of the body. Among the vertebrate sub-group of chordates the notochord develops into the spine, and in wholly aquatic species this helps the animal to swim by flexing its tail. WebThe heart is divided into chambers that work together to pump blood. There are between two and four chambers in the vertebrate heart. With more chambers, there is more oxygen in the blood and more vigorous pumping action. Most vertebrates have skin covered with scales, feathers, fur, or hair.
