Kelp forests

Large seaweeds (algae) belonging to the brown algae (Phaeophyceae) in the order Laminariales. Similar ecological characteristics as seagrass meadows but much higher primary productivity. High growth rates (0.5 meters/day) up to 30-80m tall. Growth occurs at the base of the meristem, where the blades and stipe meet. Require nutrient-rich water with temperatures between 6 and 14 °C
