Where
seen? This hard coral with branched tentacles and white
tips is sometimes seen on some of our undisturbed Southern shores.
Features: The colony appears to
be boulder-shaped, those seen about 20cm or larger. But the colony
is not solid (massive). Hidden under the tentacles, the large corallites
are branching and trumpet-shaped (phaceloid): long column flaring
out at the top (2-3cm). 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) are branched at the tips into
masses of ball-shaped and U-shaped tips. Thus resulting in its common
name. Colours seen include green and brown with white or bluish tips.
Sometimes confused with other Euphyllia species. Here's more on how
to tell apart the Euphyllia species.
Status and threats: This coral is listed as globally Vulnerable 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.
