Spiky flowery soft corals
awaiting identification*
Family Nephtheidae
updated Feb 11
Where seen? This flowery soft coral with spikes is very commonly seen on Tuas, and also sometimes seen on other shores. On coral rubble near living reefs.

Features: Colony bushy about 6-12cm. Colony is branched with 'stems' emerging from a central 'trunk'. The 'stem' white or transparent, with sclerites embedded in the tissues. The polyps appear in clusters at the tips of the branches. Polyps tiny (about 0.5cm) with eight branched tentacles. The polyps may be white, beige, yellow, orange to purple and maroon.

There are spikes next to the polyps that are nearly as large as the polyps. The spikes are more obvious when the polyp tentacles are retracted and the polyps curl up into little balls. This happens when the colony is out of water.

Flowery friends: Tiny animals may be found on spiky flowery soft corals. These include tiny false cowrie snails, tiny red-nose shrimps and tiny colourful brittle stars.
