Scientific name, Macrocystis pyrifera. Giant kelp is common along the coast of the eastern Pacific Ocean, from Baja California north to southeast Alaska, and is also found in the southern oceans near South America, South Africa, and Australia. It is the largest seaweed in the world. It could grow 150 feet long at a rate of 2 feet per day. Habitat for more than 700 species (i.e. fishes and invertebrates). In a study near San Diego, California (USA), maximum lifespan recorded for a Macrocystis pyrifera was about five years (Dayton et al. 1992). At the beginning of World War I, kelp was harvested in Chula Vista for gunpowder production. The building is now the Living Coast Discovery Center (http://www.chulavistaca.gov/City_Services/Community_Services/Nature_Center/About/history.asp) You can find alginate, and other brown algae compounds in ice cream, salad dressing, chocolate milk, shampoo, and other edible and cosmetics products.
