Explanation:

Sponges are simple multicellular animals They are all aquatic and some are attached to rocks at the bottom of the water bodies and so do not move about.Sponges have pores which water passes through into the central cavity of the animal. Their cells are loosely arranged in a gelatinous matrix called the mesophyll. This is their connective tissue.

Sponges have skeleton consisting of spicules , which vary in shape and composition. Some are made up of calcium carbonate, silica or collagen .

They do not posses true tissues or organs. They excrete and respire by diffusion. They do not have a nervous system.
