porifera:
1.reproduction is both a sexual by budding and gemmules and sexual through fertilization. possess great power of regeneration
2.mouth, digestive cavity and anus absent .
3.simplest multicellular, diploblastic animals .
4.asymmetrical or radially symmetrical .
5.body is perforated with numerous pores .
annelida:
1.body triploblastic ,bilaterally symmetrical ,soft, elongated, vermiform and cylindrical or dorsoventrally flattened.
2.alimentary canal is tube like, complete and extends straight from mouth to anus .
3.reproduction is bisexual means .
4.they live in a variety of habitats .
5.The Nervous system consists of a dorsr brain and a ventral nerve cord having ganglia and Lateral nurves in each body segment .
coelenterata:
1.aquatic ,mostly marine
2.body shows radial symmetry .
3.respiratory ,circulatory and excretory organs are absent .
4.nervous system is primitive, has only network of Nerve cells
5. many forms possesses a hard exoskeleton of lime to form corals .
Arthropoda:
1. triploblastic ,bilaterally symmetrical and metamerically segmented animals .
2.each body segment usually bears paired lateral and jointed legs
3.respiration through general body surface by gills, air tubes or book lungs .
4.fertilization is generally or usually internal .
5.Arthropoda forms the largest Phylum of animal kingdom. about 900,000species are known •
