fern red seaweed
Mats of this tiny seaweed with tiny fern-like blades are sometimes seen on
moist areas in our natural rocky shores, often among other tiny seaweeds.
Elsewhere, it is commonly seen on the intertidal zone especially near
mangroves and on mangrove roots, often forming thick bands in association
with barnacles on the upper intertidal zone.
Features: Clusters of tiny feathery,
fern-like blades (0.5-1cm), tightly packed together, forming a carpet
on natural rocky shores at the high water mark. Colour brown, yellowish,
reddish. Elsewhere may also be purplish. An astonishing variety of
tiny creatures are often seen in thick carpets of this seaweed.
