What are 5 examples of chordates?
Pandas, crows, sharks, salamanders, alligators, sea squirts, and many others are examples of chordates. So, in essence, to answer the question, amphibians, reptiles, and mammals comprise which group? — the answer is simply they belong to the phylum Chordata.
What supergroup is Chordata in?
The Chordata and Ambulacraria together form the superphylum Deuterostomia. Chordates are divided into three subphyla: Vertebrata (fish, amphibians, reptiles, birds, and mammals); Tunicata or Urochordata (sea squirts, salps); and Cephalochordata (which includes lancelets).
What are the 5 Synapomorphies of chordates?
All chordates possess 5 synapomorphies, or primary characteristics, at some point during their larval or adulthood stages that distinguish them from all other taxa. These 5 synapomorphies include a notochord, dorsal hollow nerve cord, endostyle or thyroid, pharyngeal slits, and a post-anal tail.
What are the 8 classes of Chordata?
Phylum – Chordata – Division In Vertebrata: Cyclostomata, Pisces, Chondrichthyes, Osteichthyes, Amphibia, Amphibia, Reptilia, Aves, Mammalia.

Chordate/Lower classifications
What are the different classes of phylum Chordata give one example each?
There are several classes of chordates, including, fish, birds, reptiles, mammals and amphibians.
- Class Reptilia. Reptiles are animals that have scaly, water-resistant skin, lay shelled eggs and breathe air.
- Class Amphibia.
- Class Chondrichthyes.
- Class Agnatha.
- Class Mammalia.
What are the Synapomorphies of vertebrates?
Vertebrate synapomorphies:
- Head including:
- Lateral -line system enervated by the accoustic nerve.
- Water pumped through pharynx by muscles instead of my ciliary action.
- The bars separating the slits of the pharynx support special gas-exchange organs – gills.
- Cartilaginous fin-rays support the fins.
What is Chordata classify the phylum Chordata up to the class with an example?
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.
What are Protochordates with example?
The subphyla Urochordata and Cephalochordata are collectively referred to as Protochordates. Examples are Amphioxus (Cephalochordata), Ascidia (Urochordata), etc.
Which one of the following is an example of Protochordates?
Subphylum Urochordata and Cephalochordata are often referred to as protochordates and are exclusively marine. – Amphioxus, also known as lancelets, in the Cephalochordata Subphylum, is a marine species in the Chordata group.
What is a synapomorphy example?
For example, the presence of mammary glands is a synapomorphy for mammals in relation to tetrapods but is a symplesiomorphy for mammals in relation to one another—rodents and primates, for example.
How many synapomorphies are there?
We identified 13 derived shared molecular markers (synapomorphies) that define clades in the vertebrate lineage and used them to resolve the phylogenetic relationships of extant jawed vertebrates.
Is Pisces a super class?
Pisces In older classifications, a superclass containing the four classes of fish: the two extant classes Chondrichthyes (cartilaginous fish, e.g. sharks) and Osteichthyes (bony fish), the extinct class Placodermi, and also the most primitive of the vertebrates of the class Cephalaspidomorphi.
What is Chondrichthyes and Osteichthyes?
Chondrichthyes is a class of jawed fishes having a cartilaginous skeleton. The class includes a diverse group of fishes including sharks, rays, skates and chimaeras. They are mostly marine fishes. The other group of fishes are bony fishes, which are included in the class Osteichthyes.
What are the different classes of phylum Chordata give one example?
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.
