Kelps are large seaweeds (algae) belonging to the brown algae (Phaeophyceae) in the order Laminariales. There are about 30 different genera.^{[citation needed]}
Kelps grow in underwater "forests" (kelp forests) in shallow oceans. The organisms require nutrient-rich water with temperatures between 6 to 14 degree celsius. They are known for their high growth rate — the genera Macrocystis and Nereocystis can grow as fast as half a metre a day, ultimately reaching 30 to 80 m.^[2]
