This photo has been viral for several years. Many of you might be surprised at the amount of plankton in just one drop of seawater. However, the title of the photo is quite confusing. In fact, you would have to filter the amount of water enough to fill a swimming pool with a special net to gather that much plankton. After the filtration, all these organisms would fit into a glass. Therefore, that much plankton can be found in dozens of tons of water – not in one drop. Besides, you can see the side of a Petri dish in this photo.
