COPEPOD
Scientific name: Copepoda
Kingdom: Animalia
Phylum: Arthropoda
Class: Maxillopoda
Order: Calanoida
Copepods are tiny crustaceans that generally range in
between 1-5 millimeters long. There are many different
species of these zooplankton and they live in a diverse range of environments. They are the most
abundant metazoans on Earth (Walter, 2016). Generally these organisms have a pill-shaped body and
two long antennae, along with rami on the opposite end. Their bodies are typically segmented into
multiple parts and each organism has a tiny exoskeleton. Copepods are found worldwide in most water
sources, even ones with extreme conditions. Phytoplankton are the copepods primary food source and
their predators are mostly small marine animals like shrimp, krill and fish. Copepods are incredibly
important to the carbon cycle because they reduce the carbon dioxide from the atmosphere into
carbon sinks (carbon sequestration), contributing to the biological pump.
