Marine life live in the water column of large bodies of water and that cannot swim against a current. They provide a crucial source of food to many large aquatic organisms, such as fish and whales. These organisms include drifting or floating bacteria, archaea, algae, protozoa and animals that inhabit, for example, the pelagic zone of oceans, seas, or bodies of fresh water. Essentially, plankton are defined by their ecological niche rather than any phylogenetic or taxonomic classification. Though many planktonic species are microscopic in size, "plankton" includes organisms covering a wide range of sizes, including large organisms such as jellyfish. The
Dunaliella strain is reported to have oil yield of about 37% (organic basis). "D. tertiolecta" is a fast-growing strain and that means it has a high CO sequestration rate as well. Dunaliella Dunaliella is a genus of the algae family Dunaliellaceae. "Dunaliella" sp. are motile, unicellular, rod to ovoid shaped (9−11 µm) green algae (Chlorophyceae), which are common in marine waters. The organisms are relatively simple to cultivate and do not clump or form chains. The best-known species is the extremely salt tolerant "Dunaliella salina" Teodor. A new species of "Dunaliella" was discovered in the Atacama Desert in 2010. It is
