Where
seen? This rather bumpy and knobbly sea fan is often seen
on Beting Bronok and Changi. On coral rubble.
Features: 10-15cm long. Colony
comprises a few stems branching on one plane. The branches emerge
at right angles then curve upwards. Stems are cylindrical with rounded
tips. Colours seen include red, maroon, pink and orange. The polyps
are rather large, and pinkish or orange with white centres. When the
colony is out of water and the polyps are retracted, the stems look
bumpy and gnarled. With the polyps extended, the colony looks rather
fluffy.
Animals seen on the sea fan include Winged oysters and squid egg capsules. |
