In this article we will discuss about the examples of vertebrate chordates. The first vertebrates were fishlike. Fishes are aquatic, gill-breathing vertebrates that usually have fins and skin covered with scales. The larval form of a modern-day lamprey, which looks like a lancelet, may resemble the first vertebrates- it has the three chordate characteristics (like the tunicate larva), as well [...]
In this article we will discuss about the classification of phylum chordata with its characters. The chordates form a large heterogeneous group of members differing widely from one another in many respects. Due to great diversity in chordate forms, different schemes of classification have been proposed by a number of taxonomists from time to time. The classification followed is simplified [...]
In this article we will discuss about the diagnostic features of chordata. Phylum Chordata, the largest of the deuterostome phyla, is a diverse assemblage of marine, fresh water and terrestrial animals. The chordates are triploblastic, bilaterally symmetrical, metameric, coelomate organisms with anteroposterior and dorsoventral axes. It includes sea squirts, amphioxus, cyclostomes, fishes, amphibians, reptilians, birds and mammals. All possess three [...]
