More than 25,000 species of algae live everywhere - in water, in soils, on rocks, on plants. They range in size from a single cell to giant kelp over 150 feet long. Macroalgae are large like seaweeds. Microalgae are microscopic. Ocean microalgae, called phytoplankton, are the base of the ocean food web.

There are family species of microalgae such as blue-green algae spirulina and aphanizomenon, and green algae chlorella and dunaliella. Spirulina's scientific name is arthrospira platensis. This edible algae has a long history of safe human consumption and over 30 years of safety testing. Special farms where spirulina is cultivated under controlled conditions do not allow the growth of other contaminant blue-green algae, as in lakes and waterways.
