Sea sponges can only survive in saltwater, so if you put them in freshwater, they will quickly die. They are also very sensitive to air and do not like to be taken out of the water because their pores get filled with air. If too many of their pores are filled with air, they will die.
Some real sea sponges are still sold today, used for everything from cleaning car and boat exteriors to removing make-up and exfoliating the skin. The product of at least 700 million years of evolution, sea sponges are among the world's simplest living organisms.
Synthetic sponges are made of three basic ingredients: cellulose derived from wood pulp, sodium sulphate, and hemp fiber. Other materials needed are chemical softeners, which break the cellulose down into the proper consistency, bleach, and dye.

Sea sponges are harvested by divers using specially designed cutting hooks or knives. These leave enough of the base of the sponge for it to quickly regenerate. Once cut, the divers gently squeeze the gurry out of the sponge and take them back to the boats.The pointed sponge spicules function as one method of defense against predators. Sponges also defend themselves by producing chemically active compounds. Some of these compounds are antibiotics that prevent pathogenic bacterial infections, and others are toxins that are poisonous to predators that consume the sponge.
