bright green filamentous seaweed is commonly seen on many of our shores.
The seaweed may dominate some shores at certain times of the year,
to form a bright green furry, short-pile carpet over rocks and stones.
Clumps are sometimes seen on sandy areas.
Features: Clumps of flexible,
translucent tubes about 3-8cm to 10cm long, 0.2-0.5cm in diameter.
The tubes only branch at the base. Usually bright green. This seaweed
grows abundantly in nutrient-rich waters.
The seaweed is found pretty much throughout the world in all the oceans,
estuaries and even some freshwater habitats. It is also among the
organisms that commonly grow on ship bottoms, known as fouling organisms
as they are considered a nuisance.
Other members of the Family Ulvaceae can go through a stage in their
life cycle where they resemble Enteromorpha. In fact, some
scientists believe Linnaeus was right all along: that Ulva
and Enteromorpha are actually the same genus.
According to AlgaeBase,
there more than 90 current Enteromorpha species.
Identification of the species is difficult because the internal and
external features used to distinguish among the species can vary with
age, salinity, nutrient level, amount of sunlight, wave and tidal
Human uses: Some species are eaten by people, the fine
mossy ones used to garnish dishes in Japan and some parts of China.
They are also used as animal feed, fertiliser and as medicine for
their antibacterial properties.
