Cabbage
coral
Trachyphyllia geoffroyi
Family Trachyphylliidae
updated
Oct 11
Where
seen? This beautiful hard coral is rarely seen on our shores,
and usually seen alone. The Family Trachyphylliidae comprises only
one genus and species: Trachyphyllia geoffroyi. The Cabbage
coral is said to be found with other free-living corals like mushroom
corals (Family Fungidae) in muddy bottoms of protected lagoons,
in seagrass beds, and sandy bottoms near the base of reefs.
Features: The skeleton has a meandering
folded form (flabello-meandroid) such that the entire coral resembles
a cabbage (15-20cm). Walls are tall, thin forming deep, wide valleys.
The walls have fine teeth. While young ones may be attached to a hard
surface, older ones are free-living. The base may be cone-shaped to
help it burrow into the ground. It is sometimes also called the Banana
coral by divers because, when submerged, the tissues inflate many
times the size of the skeleton, forming smooth curved shapes that
is said to resemble bananas. The polyp tentacles are short and usually
only expanded at night. It has many mouths, located in the valleys.
It is sometimes flourescent. Colours seen include brown, green and
blue.
Status and threats: The Cabbage
coral is listed as globally Near Threatened by
the IUCN. Like other creatures of the intertidal zone, they are
affected by human activities such as reclamation and pollution. Trampling
by careless visitors, and over-collection also have an impact on local
populations. |
