Hypnea sp. *
Forming clumps of tangled, fine branches, this seaweed is sometimes seen on coral
rubble on our Southern shores.
Features: Clumps of fleshy 'stems'
finely branched in tangles. Some have short 'stems' (3-6cm) covered with lots
of tiny pointed projections that give a prickly look. These may carpet
small areas of coral rubble. Others have longer stems (10-15cm) and
form tangled bunches. Colours range from beige, pink, reddish or brownish.
Bluish ones with thicker stems that form spiky
balls is probably Hypnea pannosa.
According to AlgaeBase:
there are more than 50 current Hypnea species.
Human uses: In some places, Hypnea
seaweeds are fed to livestock and eaten by people.
