$\underline \mathbb{ANSWER}$

$\bold{\fbox{\color{Red}{<klux>PHYLUM</klux>-Porifera}}}$

》Members of this Phylum are commonly known as sponges and are generally Marine and asymmetrical.

$\bold{\fbox{\color{Red}{Phylum-Coelentrata}}}$

》They are aquatic , mostly Marine, sessile or free swimming radially symmetrical animals.

$\bold{\fbox{\color{Red}{Phylum-Ctenophora}}}$

》 Ctenophores is commonly known as sea walnut or comb-jellies exclusively marine, radially symmetrical, triploblastic organism with tissue level of organisation.

$\bold{\fbox{\color{Red}{Phylum-Platyhelminthes}}}$

》 They have dorso-ventrally flattened body hence, are called flatworms. They are mostly endoparasites found in animals including human beings.

$\bold{\fbox{\color{Red}{Phylum-Aschelminthes}}}$

》 The body of aschelminthes is circular in CROSS SECTION and hence, the name roundworms. They have organ system level of body organisation.

$\bold{\fbox{\color{Red}{Phylum-Annelida}}}$

》They maybe aquatic and Terrestrial, free living and sometimes parasitic. They exhibit organ system level of body organisation and bilateral symmetry.

$\bold{\fbox{\color{Red}{Phylum-Arthropoda}}}$

》This is the largest Phylum of animalia which includes insects . They are bilaterally symmetrical , triploblastic , segmented and coelomate animals.

$\bold{\fbox{\color{Red}{Phylum-Mollusca}}}$

》This is the second largest animal Phylum.They are Terrestrial or aquatic having an organ system level of organisation.

$\bold{\fbox{\color{Red}{Phylum-Echinodermata}}}$

》 These animals have an endoskeleton of calcareous ossicles and hence the name echinodermata. All are marine with organ system level of organisation.

$\bold{\fbox{\color{Red}{Phylum-Hemichordata}}}$

》Hemichordata was earlier considered as a sub-Phylum under Phylum chordata but now it is placed as separate Phylum under non chordata.

$\bold{\fbox{\color{Red}{Phylum-Chordata}}}$

》Animals belonging to Phylum chordata are fundamentally characterized by the presence of a notochord, a dorsal hollow nerve cord and paired parapharyngeal gill slits.

$\bold\green{\underline{Class:Cyclostomata}}$

》All living members of this class cyclostomata are ectoparasites on some fishes. They have an elongated body bearing 6 - 15 pairs of Gill slits for respiration.

$\boxed {EXAMPLE:-}$

~Petromyzon , Myxine

$\bold\green{\underline{Class:Chondrichthyes}}$

》 They are marine animals with streamlined body and have cartilaginous endoskeleton.

$\bold\green{\underline{Class:Reptilia}}$

》This class has creeping or crawling mode of locomotion. They are mostly Terrestrial animals and their body is covered by dry and cornified skin , epidermal scales or scouts.

$\boxed {EXAMPLE:-}$

$\bold\green{\underline{Class:Aves}}$

》A characteristic feature of aves is the presence of feathers and most of them can fly EXCEPT flightless birds.

$\boxed {EXAMPLE:-}$

~ Corvus , Columba

$\bold\green{\underline{Class:Mammalia}}$

》 They are found in a variety of habitats polar , ice caps, desert , mountain, forest Grassland and DARK caves. Some of them have adapted to fly or live in water . The most unique mammalian characteristic is the presence of milk producing glands by which the young ones are nourished.
