kingdom animalia have phylum 
1 *phylum porifera they pocess cellular level organisation.some tissue
* they have holes in there body.
*they are also called sponges.
*the body design of these animals involves minimal differentiation.
*non mortal animals attacted to sme solid support.
*water driven tube system for transportation of food and water.
*they are marine .
*eg spongilla
2* phylum coelenterates pocess tissue level  organisation.
*they body has a single opening.

*the exceretory organ called nephridia
*resiration through skin
* bilaterally symmetry 
segmented 
eg earthworm
6 phylum arthropoda is largest group
*bilaterally symmetical
*segmented
*open circulatory system
*joined legs
*eg spider
7 mollusca has open circulatory system
*kidney like structure
*foot like structure for movement
*segmented 
*bilaterally symmetrical
*not  colemate
eg octupus
8 echinodermata echino means hedgehg derma means skin
*spiny skinned organism
*these body is cvered with hard calicum carbonate
*bilaterally symmterical
*triploblastic
*pecuilar water driven system
eg star ish
9 protochondata hae notochord
*bilaterally symmterical
eg balanoglossus
