Where
seen?
These solitary stalked green fans are sometimes seen on some of our
shores, sticking out of the ground here and there. Usually in coral
rubble areas.
Features: A paddle-shaped blade
(4-5cm wide), usually growing alone, sometime a few near one another.
The blade is flat and not ruffled. The flexible blade is made up of
a tangle of tiny filaments that give it a velvety texture. The blade
is held up on a stiff stalk that may be buried in sand or wedged into
crevices.
The stalk can be quite long (up to 10cm long), with only a short portion
sticking out above the surface. Sometimes, the single blade is divided
into three or four 'wings'. Usually dark green sometimes with pale
or yellowish edges.
