Calcarea (calcareous sponges) live excusively in marine waters at depths generally not exceeding 100 meters. They have a skeleton made up of calcareous spicules.
Porifers are marine and freshwater animals which filter water for food. Their surface is pierced with a multitude of small pores through which
water enters, and fewer and wider openings, the oscules, through which water is drained (hence their name Porifère: from the Greek por- = passage).
