Giant kelp - Macrocystis pyrifera

Giant kelp along the surface indicates a favorable slack tide for diving. When the current picks up, Macrocystis pyrifera disappears under the surface as it is stretched out in response, suggesting a good time to find a safer dive site. It is one of the fastest growing organisms on earth, sometimes reaching 150 ft in length and can grow 2 feet a day.
