Carbon Sequestration Facilitates the ocean's ability to store carbon dioxide. Krill are the primary consumers that feed directly on this phytoplankton, transforming solar energy into a protein-rich biomass that other species can utilize.
Krill Central Role in the Antarctic Food Web and Carbon Cycling
Ecosystem Engineers and Carbon Cycling Beyond simply being food, krill play a vital role in the ocean's biogeochemical cycles. Nutrient Recycling Recycles iron and other nutrients to boost phytoplankton growth.
The Engine of the Marine Food Web The Southern Ocean’s productivity is driven by phytoplankton, microscopic plants that convert sunlight into energy. While the current catch is regulated, it highlights the commercial value of krill.
Krill: The Central Pillars of the Antarctic Food Web
These small, shrimp-like crustaceans form the foundational link between microscopic phytoplankton and the largest animals on Earth, such as baleen whales and penguins. Tiny fish and jellyfish consume the nauplius larvae of krill, while these larvae grow into dense swarms that can be tracked from space.
