- This article is about the animal. For other uses, see Sponge (disambiguation).
The sponges or poriferans (from the Greek poros "pore" and ferro "to bear") are animals of the phylum Porifera. They are primitive, sessile, mostly marine, water dwelling filter feeders that pump water through their bodies to filter out particles of food matter. Sponges are among the simplest of animals. With no true tissues (parazoa), they lack muscles, nerves, and internal organs. Their similarity to colonial choanoflagellates shows the probable evolutionary jump from unicellular to multicellular organisms. There are over 5,000 modern species of sponges known, and they can be found attached to surfaces anywhere from the intertidal zone to as deep as 8,500 m (29,000 feet) or further. Though the fossil record of sponges dates back to the Precambrian era, new species are still commonly discovered.

It's weird that Spongebob has a pet snail. Mollusks are much more complex organisms than porifera. Really, Gary should have a pet sponge.
