Asparagus
sea fan
Dichotella cf. gemmacea*
Family Ellisellidae
updated Dec 2019
Where
seen? This sparsely branched brightly coloured sea fan
is often seen on Beting Bronok and sometimes at Changi, on rubble
and rocks.
Features: 15-20cm long. The colony
comprises a cluster of a few cylingrical stems that are generally
unbranched except near the base. Polyps with white transparent tentacles.
When they retract, the base of the polyps curve to form smooth bumps
so the stem resembles asparagus. Usually bright red, but sometimes
also white, yellowish or orange.
There are also long unbranched sea whips that
look like asparagus sea fans. |
