hoon' green seaweed
This green seaweed does look like our local noodle favourite, 'bee
hoon' (vermicelli)! It is seen on many of our shores, growing entangled
among seagrasses or other seaweeds. It 'blooms' seasonally, sometimes
drifting up on the shores in large tangled bundles. It may also form a bright green mossy carpet under
Features: Filaments fine, long
(40cm or more) and unbranched that grow entangled among other seaweeds.
Each filament is made up of a single row of cylindrical cells joined
together end to end. The cells are longer than they are wide: thus
the filament resembles bamboo when seen under a microscope. Bright
light green to dark green, sometimes olive green.
According to AlgaeBase,
there are more than 50 current Chaetomorpha species.
Sometimes confused with Hairy
green seaweed (Bryopsis sp.) which has much shorter filaments
and appears feathery. Here's more on how
to tell apart some green seaweeds.
Human uses: It is used as animal
feed and eaten raw by people.
