A sponge is an animal that lives in the sea. They feel very spongy.[citation NOT needed]

Significance to the evolution of multicellular life[edit]

This experiment shows that single-celled organisms may have formed multicellular ones. First get a sponge, and chop it up into several small pieces. These pieces are then forced through a sieve so fine it separates the individual cells that make up the animal. Then, view it through a microscope to see the individual cells clumping together. After waiting for a while, the cells will clump to form the original multicellular organism.[1] This does not work with goats.[citation NOT needed]

Furthermore, if you were to do the same experiment, but mix up the cells of different species of sponges, the sponges would all assemble into their separate species.
