Not much attention is paid to plankton because these creatures are usually hidden from sight. They are mostly microscopic in size and live in aquatic environments, but human lives are intricately connected with plankton.
The etymology of “plankton” originates from the ancient Greek word for “drifter.” Plankton refers to all organisms suspended in all types of waters (oceans, lakes, rivers and even groundwaters), including viruses, bacteria, insects, larval fish and jellyfish. Plankton come in many shapes and sizes, but what unites all of them is a tendency to drift with currents.
