About the Phylum Porifera
The word "porifera" comes from the Latin porus, or pore, plus ferre, to bear. The word refers to the fact that the surface of a sponge's body is covered with tiny pores. With neither true tissues nor organs, sponges are the most primitive of multicellular animals.
Bath Sponge (Spongia officinalis)
Bath Sponge (Spongia officinalis)
Native to the Mediterranean and Caribbean seas, it is the skeleton of this sponge that becomes the familiar natural bath sponge. Once harvested from the sea bed, most are now raised on "sponge farms."
