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. |
