Chordata
Top > Biology > Biota > Fauna > Chordata
Chordates (Chordata) are animals with a backbone (notochord), a dorsal hollow nerve cord, pharyngeal slits, an endostyle, and a post-anal tail. They include animals with backbones (vertebrates, Chordata) and animals lacking a vertebral column (tunicates and lancelets, Tunicata and Cephalochordata). We provide comprehensive descriptions including morphology, life cycle, and other biological features of chordates which include familiar animals and humans themselves.
