What are the 7 classes of non Chordata?
Members of phylum Porifera, Coelenterata, Ctenophora, Platyhelminthes, Aschelminthes, Annelida, Arthropoda, Mollusca, Echinodermata and Hemichordata fall under Non-chordates.
What is a chordate class?
Chordata contains five classes of animals: fish, amphibians, reptiles, birds, and mammals; these classes are separated by whether or not they can regulate their body temperature, the manner by which they consume oxygen, and their method of reproduction.
Which is link between chordates and non chordates?
Balanoglossus is the connecting link between chordates and non-chordates.
How are chordates and non chordates difference write in two points?
Chordates and Non-chordates are primarily differentiated by the presence or absence of an important structure called the notochord at some point in their lifecycle.
What is the difference between chordates and Hemichordates?
Hemichordates are worm-like, marine animals while chordates live in water, land, and air. The main difference between Hemichordata and Chordata is that Hemichordata contains an epidermal nervous system whereas Chordata contains a central nervous system. Both Hemichordata and Chordata contain pharyngeal gill slits.
What are the 8 classes of chordates?

Is Chordata a class?
We can define chordate as follows: “The chordates are the class of animals that possess four anatomical features, namely (1) notochord, (2) dorsal nerve cord, (3) post-anal tail, and (4) pharyngeal slits, at least during some part of their development into maturity.”
What are chordates class 9?
Phylum Chordata belongs to the Kingdom Animalia and includes all the vertebrates, i.e., animals with a backbone, and several invertebrates, i.e., organisms without a backbone. They possess a bilaterally symmetrical body and are divided into three different sub-phyla.
Which phylum of Kingdom Animalia is the connecting link between non Chordata and Chordata II give reason why is it called so?
Balanoglossus is considered a connecting link between chordates and non chordates because it shows characteristics which are present in both the phylums. For example, Balanoglossus shows the presence of notochord and pharyngeal gill slits which is a characteristic feature of chordates.
Which is connecting link between Annelida and Arthropoda?
The body of Peripatus shows certain structures that are similar to annelids and other structures found in arthropods. Therefore, they are regarded as the connecting link between Annelids and Arthropods.
