Is there more krill or plankton in the ocean?

    Krill are plankton. Specifically zooplankton. “Plankton” is not actually a type of organism — is basically any of the untold number of species of invertebrates, algae, larvae, etc. that float around mostly at the mercy of the water’s motion. Krill are small, shrimp like animals comprising many different species in and of themselves. There’s been some debate about whether or not krill are “true” plankton because of their increased mobility, but they are plankton for all practical and biological purposes.
