Info from Licensor: "This video shows non-toxic dye being used to show how efficient sponges can circulate water through their bodies. Sponges filter plankton and oxygen out of the water by sucking in the water through the outside and discharging the wastewater out through the chimney-like center of the sponge. Due to the lack of food and oxygen in the water, you rarely find anything inside of sponges. You can see how quickly the dye moves from the outside of the sponge and out through the center exhaust area. This happens very quickly."
