Carnation
leathery soft coral
Awaiting identification*
Family Alcyoniidae
updated Dec 11
Where
seen? Resembling leathery carnations with
polyps like little glass stars, this soft coral is sometimes seen
on some of our shores. Among coral rubble and sandy areas near reefs.
Features:
The
colony (10-15cm) is usually thick, disk-like with highly ruffled ridges.
Sometimes covering large areas of 50cm or more.The
common tissue may be purplish grey, beige, yellowish or blue. Polyps
may be colourless or faintly coloured green, yellow.
It has only one kind of polyp (autozooid) although there are very
tiny spots among the autozooids giving the leathery common tissue
has a rather 'crystalline' appearance. The transparent polyps are
tiny (0.2cm), 8 short cylindrical tentacles with tiny branches, the
body column hardly seen. The autozooids are only found on the upper
side of the common tissue and tend to be clustered on the edges of
the disk, with fewer in the middle of the disk. The autozooids emerge
from small lumps or even long tubular segments of the common tissue.
The autozooids can retract completely into the common tissue.
Leathery soft corals that have these characteristics include Dampia
sp. and Sinularia brasicca.
