Ecklonia maxima, or sea bamboo, is a species of kelp native to the southern oceans. It is typically found along the southern Atlantic coast of Africa, from the very south of South Africa to northern Namibia. In these areas the species dominates the shallow, temperate water, reaching a depth of up to 8 metres (26 ft) in the offshore kelp forests. The species is of economic importance as it is harvested for both an agricultural supplement and as food for farmed abalone.
