Torch
anchor coral
Euphyllia
glabrescens*
Family Euphylliidae
updated
Nov 2019
Where
seen? This small hard coral that resembles a cluster of sea anemones
is sometimes seen on our undisturbed Southern shores.
Features: The colony appears to
be boulder-shaped, those seen 10-20cm, sometimes much larger. But
the colony is not solid (massive). Hidden under the tentacles, the
corallites are branching and trumpet-shaped (phaceloid): long narrow
column flaring out at the top (1-2cm). The branching corallites are
arranged with the broad, flared portions facing out to form an overall
spherical shape. But this feature is usually hidden when the polyps'
long tentacles are expanded. Tentacles long (2-3cm) with a rounded
white tip (not U-shaped). Colours seen beige, brown or blue with white
tips.
Sometimes confused with other Euphyllia species. Here's more on how
to tell apart the Euphyllia species.
With their tentacles fully extended, torch corals may also resemble Sunflower mushroom corals (Heliofungia actiniformis). The torch coral, however, has much
shorter tentacles and of course an entirely different skeleton structure.
Status and threats: This 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. |
