Giant kelps

Giant kelps are the largest of the kelps, which in turn are the most complex kinds of brown algae. Reaching lengths of 45m long, kelps need a rocky seabed to attach themselves to. In ideal conditions where the water is clean, clear and nutrient-rich, giant kelps can grow at a rate of 36cm a day, making them the fastest growing of the algae.
