What are the 6 classes of Chordata?
The classes of the Phylum Chordata are the Amphibia, the Reptilia, the Fish, the Birds, and the Mammalia. Amphibians include frogs, salamanders, toads, newts, and some less familiar animals, such as caecilians.
What are three different classes under the Chordata phylum?
Phylogeny of Chordates 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.
What are the seven classes of vertebrate?
|Agnatha (Jawless Fish) Aves (Birds) Amphibia (Amphibians) Chondrichthyes (Rays, Sharks, Skates)||Mammalia (Mammals) Osteichthyes (Bony Fish) Reptilia (Reptiles)|
What are the 7 classes of phylum?
The Animal Kingdom contains these seven Phyla: Porifera, Cnidaria, Platyhelminthes, Annelida, Mollusca, Arthropoda, and Chordata.
Which class of chordates existed first on earth?
The earliest chordates were all marine animals like tunicates and lancelets. As chordates continued to evolve, they spread to freshwater habitats and ultimately to land. The amphibians represent an intermediate phase in the water to land transition of chordates.
How many classes are under Chordata?
The phylum Chordata contains all of the animals that have a rod-like structure used to give them support. In most cases this is the spine or backbone. Within Chordata there are five classes of animals: fish, amphibians, reptiles, birds, and mammals.
What are the features of the 5 vertebrate groups?
Characteristics of the Five Vertebrate Groups
- Fish. The body of the fish is covered in scales and has fins attached to help it move through the water.
- Amphibians. The skin of amphibians is very thin and must always be kept wet because amphibians breathe through their skin.
Is snake a vertebrate?
Snakes belong to the vertebrates, along with all other reptiles and amphibians, mammals, birds, and fish. All these animals have an inner skeleton. Bones give structure and strength to bodies. Muscles are attached to bones, and this enables us to move as our muscles contract.

What are the five classes of chordates?
Chordata Phylum . Chordata are typically known to have spines (they are vertebrates). The most primitive chordates had no spines, but quickly developed. Chordates are classified into 5 classes: Mammals, Fish, Amphibians, Birds, and Reptiles.
How many classes of chordate are there?
Phylum Chordata is classified into three subphyla, namely. Urochordata (tunicates), Cephalochordata ( lancelets ) Vertebrata (vertebrates).
Which characteristic is common to all chordates?
All invertebrate chordates share four main characteristics: a notochord, a dorsal nerve tube, a post-anal tail, and pharyngeal gill slits. All of these characteristics are observed at some point in chordate development.
What are some interesting facts about chordates?
Facts about Chordates tell the readers about the animals included in phylum Chordata . The physical characteristics of Chordates are noticed on the presence of a post-anal tail, pharyngeal slits a notochord, an endostyle and a hollow dorsal nerve cord. The anus of chordates will be formed before the mouth. Therefore, it is included as deuterostomes.
