Porifera also known as sponges, are the simplest and oldest of multicell animals that can be found on the sea floor. The term “Porifera” refers to pore bearing species and have a spongy appearance. This unique animal called “Poriferan” do not have any organs nor tissues on its body, but each individual cell will digest its own food. In order for Poriferan to survive, they need a constantly moving water to bring them food. The water will move through their channel from the bottom carrying food and oxygen, passing through the cells for digestion while the waste will be pumped out through the top of the channel. Porifera are not corals as corals are complex animals and Porifera can be found in fresh water too!
