(canal) the are 3 canal system in sponge a.ascon b.sycon c.rhagon
3(number of germ layers) 3 layers ectoderm endoderm mesoglea
(symmetry)sponge are assymetry. its a type of symmetry which has no definite shape
(habitat) they can be found in shallow or deep water fresh or salty
(spicules) its formed by the classification of materials secreted by the cell
(distuinguishing chars)the prescence of canal syatem perfprating the body wall and connecting the central body outside
1)sponges are spore bearing animals they are attached to solid materials in water
2) it is a sponge made up of exoskeleton that are made up of galss or silicon. the spicules form beautiful pattern of six wayed weaves.
