Coccolithus pelagicus

Coccolithus pelagicus is a type of microscopic marine algae known as a coccolithophore. It floats in the open ocean and helps produce a significant portion of Earth's oxygen through photosynthesis. This organism is characterized by tiny calcium carbonate plates called coccoliths that form a protective layer around it, giving it a distinctive appearance under the microscope. Coccolithus pelagicus plays a crucial role in the ocean’s carbon cycle, as its coccoliths can sink and sequester carbon in sediments, impacting climate regulation. It thrives in cold, nutrient-rich waters and is an important component of marine ecosystems.
