fan green seaweed
This smooth fan-shaped seaweed in clusters is sometimes seen on some
of our Northern shores, growing on and among coral rubble. Elsewhere
also in sand. It was previously known as Udotea javensis.
Features: A long fan- or spatula-shaped
blade (2-3cm long) that are thin and floppy without ruffled edges although
the thin blades may be folded in pleats, in clusters of several blades.
The blade is made up of a tangle of tiny filaments that give it a
velvety texture and is slightly to moderately calcified. The stem
that holds up the blade (stipe) is calcified. Usually
Sometimes confused with other fan-shaped green seaweeds.

Human uses: Some species have
anti-bacterial and anti-tumor properties.
