Invertebrata: It includes group of animals that do not possess a vertebral column. Invertebrata is classified into different phyla such as Porifera, Coelenterata, Platyhelminthes, Nematoda, Annelida, Arthropoda, Mollusca and Echinodermata.
a) Porifera are multicellular organisms exhibiting minimal level of tissue organization. They lack nervous system. Porifera get their name from two words, “pori,” meaning “holes,” and “fera,” meaning “bearing”. Porifera includes Sycon, Spongilla and Euplectella. e.g. Sponges.
Porifera are primitive, multicellular, asyymetrical, marineorganisms exhibiting minimal level of tissue organisation.Body is supported by skeleton made up of spicules or sponging fibres.Water vascular system is responsible for nutrition, respiration and excretion. They lack nervous system. Poriferans are hermaphrodites and reproduce both by asexual and sexual means of reproduction. Fertilisation is internal. They exhibit indirect development. Porifera gets its name from two words, “pori,” meaning “holes,” and “fera,” meaning “bearing”.Porifera includes Sycon, Spongilla and Euplectella.e.g. Sponges.
b) Coelenterates are radially symmetrical organisms which live in marine habitat except for hydra. Some are solitude and some are colonial. Coelenterates get their name from two Greek words - “koilos,” meaning “hollow,” and “enteron,” meaning “intestine”. e.g. Corals, Hydra.
Coelenterates are aquatic, marine, sessile or free-swimming, diploblastic organisms.Coelenterates are radially symmetrical organisms exhibiting tissue level of organization.Some are solitude and some are colonial. Some coelenterates possess skeleton made up of calcium carbonate. Coelenterates possess tentacles with cnidoblasts. .
lluscs are bilaterally symmetrical, triploblastic gastropods with reduced coelom. Mollusca is derived from a Latin word, which means “thin-shelled and soft”.
Locomotion in molluscs is by means of a muscular foot. Water molluscs breathe through their gills, while land molluscs have lungsCirculatory system in molluscs is open. Snail is a small molluscan Snail is protected by its external skeleton called as shell. Snails are found in wet places. Entire body except the foot lies inside the shell. When disturbed, snail even retracts the foot in to the shell. Snail moves with the help of single muscular foot. The under surface of the muscular foot is lubricated with mucus. The muscular foot glides over the surface. The rhythmic contractions and relaxations of this muscular foot brings about pulling action in the body. The secreted mucus also reduces the risk of injury from sharp objects.
h) Echinodermata are triploblastic animals with true coelomic cavity. Echinodermata are spiny skinned organisms which get their name from the Greek words “echinos,” meaning protective “spines,” and “derma,” meaning “skin”. Skeletons of echinoderms are hard calcium carbonates. They exhibit radial symmetry.

Skeletons of echinoderms are hard calcium carbonates. The organisms belonging to the Phylum Echinodermata are called as echinoderms and exhibit many peculiar characters.Echinoderms exhibit pentameral radial symmetry in the body organisation.Echinoderms have special type of water vascular system with tube feet.Echinoderms are eucoelomates.Echinoderms are deuterostomes.Larvae of echinoderms are motile, bilaterally symmetrical in form. Starfish, brittle star belong to this phylum.
Protochordata: These are the organisms belonging to the phylum Chordata, and are primitive chordates. Protochordates possess a notochord during their early stage of development. The notochord is a long rod-like support that runs all along the back of the animal separating the nervous tissue from the gut. e.g.Balanoglossus, Herdmania.
Vertebrata: These are the most advanced group of animals with true vertebral column and strong endoskeleton. Vertebrates are grouped into different classes based on bilateral symmetry, notochord, dorsal nerve cord, paired gill pouches, triploblastic, and coelomate. These classes are Pisces, Amphibia, Reptilia, Aves and Mammalia.
a) Pisces includes all fish. These are aquatic cold blooded organisms with a spindle-shaped body covered by scales.

animal kingdom is divided into two groups..
nonchordates - porifera, cnidarians, ctenophora, platyhelminthes, aschelminthes, Annelida ,arthropods ,molluscs, echinoderms, hemichordates
and chordates
animal kingdom is classified on the basis of
1. no of germ layers
according to germ layers whether they r diploblast or triploblast
2. body plan
a... cell aggrergrate ...eg... -porifera
b... blind sac body plan
c... tube within tube body plan
3.coelom
acoelomates
pseudocoelomates
coelomates
4.segmentation
5.body symmetry
a. radial.
b. bilateral
c.asymmetry
