Sis forSea Sponge
Scientific name: phylum: porifera
A sponge is an animal that lives in the sea whose body is made up of lots of holes. Most sea sponges have hard skeletons, and the holes are for filtering food out of the water and so they can breathe. Some species of sponge have soft skeletons and people used to catch them to use them for cleaning and packaging, but there are now almost none left. Today, sponges found around the house are made by people, and are not animals caught in the sea.
