I found on You Tube an interesting movie about one of the tiniest living forms on earth. Even so, these living creatures, which are drifting animals organisms, feed great predators and inhabit the pelagic zone of oceans, seas or bodies of fresh water.
Plankton includes organisms with a wide range of sizes, from microscopic to jellyfish forms.
The effects of global warming, on the plankton population, has been a case study for the past decade. Dependent on light levels and nutrient availability, no doubt that the environmental variations felt lately had its impact on these fragile organisms levels.
El Nino's heat wave, for instance, produced an abnormal decreased of world level plankton influencing populations of zoo plankton, fishes, sea birds and marine mammals.
