"Emiliania huxleyi" ("Ehux" for short) is one of the most important planktonic algae on the planet today. It is the most common coccolithophore in the oceans of the world. It dominates in the northeast Atlantic, in the northeast Pacific and in the eastern Mediterranean. Its gigantic algal blooms are easily seen on satellite imagery. This blooming life-style started between ~80,000 and 50,000 years ago, and marks the start of the so-called "Ehux Acme zone" in the fossil record.
