Description
Dichotomously branching fronds up to about 15 cm long and brown or dark green in colour. Has an appearance somewhat like that of Fucus spp. but generally has more narrow fronds. Some species live 3-4 years. The fronds of some species are curled longitudinally and thus form a channel. |
Habitat
Generally found in the high intertidal zone of rocky shores. Can tolerate ultra sheltered to moderately exposed conditions. |
