Sponge Kingdom Biology. Sponges are pri­mar­ily ma­rine, but around 150 species live in fresh water. Scientists believe sponges are the oldest animal phylum. In this lesson students make a guess as to what was the first. Sponge, any of some 5,000 species (phylum porifera) of permanently affixed (sessile), mostly marine, solitary or colonial invertebrates, found from shallow to deep (more than 30,000 ft, or 9,000 m) waters. Sponges are a di­verse group of some­times com­mon types, with about 5000 species known across the world. Sponges are similar to what might have been the ancestor of animals: They have cells that are independent of each other but work together in a colony. Sponges are unusual animals that lack definite organs to carry out their various. The cnidarians, or the jellyfish and their kin, are the simplest animal group that displays true tissues, although they possess only two tissue layers. Sponges are only just classed as animals. They first appeared about 600 million years ago.
