CLASSIFICATION OF ANIMALIA:

CLASSIFICATION OF ANIMALIA PHYLUM 1 : PORIFERA PHYLUM 2 : COELENTRATA PHYLUM 3 : PLATYHELMINTHES PHYLUM 4 : NEMATODA PHYLUM 5 : ANNELIDA PHYLUM 6 : ARTHOPODA PHYLUM 7 : MOLLUSCA PHYLUM 8 : ECHINODERMATA PHYLUM 9 : CHORDATA phylum 10: VERTIBRATA

1. PHYLUM : PORIFERA ( Porus=pore; ferre=bear; sponges):

1 . PHYLUM : PORIFERA ( Porus=pore; ferre=bear; sponges) Porifera are commonly called sponges , mostly marine but may live in fresh water. Mostly sessile (stalk less) and attach to substratum . They are asymmetrical. They have cellular level organization. They have a single large opening called osculum. (intake and exit of food through a single opening). They lack mouth, digestive cavity and anus. Sponges are covered with hard outer skeleton . Reproduction is both asexual as well as sexual . Examples : sycon, euplectella , euspongia etc.

2. PHYLUM : COELENTERATA/CNIDRIA (koilos=hollow; enteron= gut):

2 . PHYLUM : COELENTERATA/CNIDRIA (koilos=hollow; enteron= gut) These all organisms are aquatic (marine or fresh water.) They may be solitary or colonial. They have tissue level of organization but lacks organ and organ system. Symmetry is radial. It has a single aperture, the mouth . It has no anus. Mouth bears tentacles (flexible processes). They have special stinging cells, called cnidoblasts for defense purposes. Reproduction is mainly asexual but sometimes undergoes sexual reproduction. Fertilization may be internal or external. Hard skeleton occurs in corals Example : hydra(fresh water polyp), obelia (the sea fur), Aurelia (jelly fish).

3. PHYLUM : PLATYHELMINTHES (platys=flat; helmins=worm; flatworm):

3 . PHYLUM : PLATYHELMINTHES (platys=flat; helmins=worm; flatworm) These are most primitive, soft, leaf or ribbon like organisms without segmentation. These are mostly parasites , few are free living. They attach to the host by suckers or hooks . They are the first animals to have third primary germ layer , this shows tissue differentiation leading to organ formation. Digestive track is incomplete. They have flame-cells for excretion . They are mostly hermaphrophite (bisexual). Examples : dugesia (planaria), fasciola (liver fluke), taenia solium (tape worms).

4. PHYLUM : NEMATODA (Roundworms):

4 . PHYLUM : NEMATODA (Roundworms) Animal body is cylindrical, flattened, bilateral, triploblastic(third layer), unsegmented. Size of the body varies from microscopic to several c entimeters in length. Body wall is covered with tough cuticle . Cilia are a bsent . Pseudocoelom (false body cavity) is present. Digestive track is complete. Sexes are separate ( bisexual ). These are generally parasites and causes diseases. They may be free living in soil or water. Examples: ascaris (intestinal sound-worm), hookworm, pinworm filarial worm.

5. PHYLUM : ANNELIDA (Annelus=a ring; segmented worms):

5 . PHYLUM : ANNELIDA (Annelus=a ring; segmented worms) Animal body is soft, elongated, bilateral, flattened. Body is divided into segments by rings like groove and annule. Body bears locomotory appendages, parapodia, setae. Alimentary canal is complete, straight and extends from mouth to anus. These are first animals to have true body cavity . The specialized cells called metanephridia helps in excretion . Closed circulatory system has appeared and nervous system starts developing. Reproduction occurs by sexual means . Sexes may be separate (unisexual) or united (hermaphroditic). Examples : nereis .

6. PHYLUM : ARTHOPDA (Arthos=jointed; podos=foot; animals with jointed feet):

6 . PHYLUM : ARTHOPDA (Arthos=jointed; podos=foot; animals with jointed feet) It is the largest phylum includes prawn, crabs, insects, spiders, etc. They occur in soil, water and as parasites in plants and animals. Body is segmented externally but not separated internally. Body is divided into 3 regions: head, thorax and abdomen . Interior part of the body forms head and bears sense organs and small brain. Sexes are separate . Hard exoskeleton is made up of cuticle . Body contains blood, alimentary canal is complete , respiration take place by gills, trachea, book lungs etc. Examples: prawn, lobsters, housefly, dragon etc.

7. PHYLUM : MOLLUSCA (molluscus = soft):

7 . PHYLUM : MOLLUSCA (molluscus = soft) It includes aquatic organisms like snails, octopus, slugs, oysters etc. Animal body is soft, unsegmented without appendages . . Body is divided into 3 regions: head, visceral mass and foot. . Sometimes body is covered by fleshy folds called mantle . . In most cases, calcarious shell is secreted by mantle which covers the body. . Alimentary canal is complete . Respiration is through gills and sexes are separate . . Examples: octopus, snail, logio, sepia etc.

8 . PHYLUM : ECHINODERMATA . These are marine , gregarious(at bottom), slow moving animals. . The shape of the animal ay be star-like, cylindrical, melon, flower-like etc. . Body is covered by spine s. True body cavity, podia for movement and all animals lacks head . . Sexes are s eparate . . Examples: asterias (starfish), holothurians (sea-cucumber), antedon (feather star)

9. PHYLUM : PROTOCHORDATA:

9. PHYLUM : PROTOCHORDATA HAVE BILATERALLY SYMMETRICAL , TRIPLOBLASTIC AND HAVE A COELOM. BODY DESIGN NAMELY NOTOCHORDATA,AT LEAST SOME STAGES DURING LIFE. MARINE ANIMALS. RESPIRATION IS TROUGH GILL SLITS. Ex:-BALANOGLOSSUS,AMPHIOXUS.
