The natural sponge (Hippospongia equina) is a simple form of life that can be found in all oceans, from the Caribbean Sea to the Arctic Ocean. Its function in the ocean is that it acts as a natural filter. It pumps water through its body to feed itself on plankton and other small food particles.
There are over 7,500 different species of natural sponges that appear in sizes from a few millimeters to about three meters high. Depending on the water temperature, depth and flow natural sponges need half a year up to 5 years to grow.
