Their body symmetry is of bilateral type. These unicellular crea­tures have therefore been placed in the subkingdom protozoa, which includes only one phylum, the protozoa. These are also called lower chordates e.g. The major groups of living reptiles—the turtles, tuataras, lizards and snakes, and crocodiles account for over 8,700 species. Non-chordates are animals without a notochord – the rod-like elastic structure that supports the body. Protostomes is any member of the lower invertebrate phyla in which the mouth appears before the anus during development, cleavage is spiral and determinate and the coelom forms as a splitting of the mesoderm. noton, back + L. chorda, cord).The animals belonging to all other phyla of the Animal Kingdom are often termed 'the non -chordates' or 'the invertebrates' since they have neither notochord nor backbone in their body. This phylum is probably the most notable phylum, as all human beingsand other animals and birds that are known to you, fall under this phylum. The remaining phyla of animals, all of which are many-celled, comprise the sub- kingdom metazoa. They are unicellular, jelly-like protozoa found in fresh or sea water and in moist soil. 1. This phylum mainly consists the insects. The hemichordates have developed pharyngotremy—an important fea­ture for chordate organisation. Understand the variety of living organisms with TopperLearning’s Frank Solutions for ICSE Class 9 Biology Chapter 13 Diversity of Life and Classification. Segmentation of the body and 6.

Presense or absence of Notochord. A chordate (/ ˈ k ɔːr d eɪ t /) is an animal of the phylum Chordata (/ k ɔːr ˈ d eɪ t ə /).During some period of their life cycle, chordates possess a notochord, a dorsal nerve cord, pharyngeal slits, and a post-anal tail: these four anatomical features define this phylum.Chordates are also bilaterally symmetric, and have a coelom, metameric segmentation, and circulatory system. Reptiles evolved from amphibians during the first part of the Pennsylvanian subperiod (323 million to 299 million years ago) and retained many amphibian structural characteristics. Chordates have a prominent notochord, whereas non chordates do not have a notochord. The animals belonging to all other phyla of the animal kingdom are often termed ‘the non-chordates’ or ‘the invertebrates’ since they have no notochord or backbone in their body structure.
