A chordate is an animal belonging to the phylum Chordata; they possess a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail, for at least some period of their life cycle.

What are the 8 classes of Chordata?

Classification of Chordates

Myxini (hagfish).
Hyperaortia (lampreys).
Chondrichthyes (cartilaginous fish).
Actinopterygii (ray-finned fish).
Sarcopterygii (lobe-finned fish).
Amphibia (amphibians).
Sauropsida (reptiles).

How is a mammal classified?

An animal is considered a mammal if it can produce milk. Other features unique to mammals include hair or fur (chemically different from hairlike structures on non-mammals); the malleus, incus, and stapes in the ear; and a diaphragm separating the heart and lungs from the abdomen.

Do chordates have bilateral symmetry?

Chordates get their name from their characteristic “notochord”, which plays a significant role in chordate structure and movement. Chordates are also bilaterally symmetric, have a coelom, possess a circulatory system, and exhibit metameric segmentation.

What is the difference between chordates and non Chordata?

The major point to differentiate between chordates and non-chordates is that chordates have a spinal cord or backbone in their body structure whereas non-chordates are without backbone or notochord in their body structure.

What is the difference between Chordata and Vertebrata?

Chordates are characterized by the presence of a notochord. The main difference between chordates and vertebrates is that some chordates do not have a vertebral column whereas all vertebrates have a vertebral column. In vertebrates, the vertebral column surrounds and protects the nerve cord.

How many different chordates are there?

There are three Chordata subphyla i.e. Urochordata (Tunicata), Cephalochordata, and Vertebrata (Craniata). The salient features on which all of these three classes have been categorized are the notochord, nerve cord, branchial slits, endostyle, postanal tail, and a myotome.
