Fire anemone
Actinodendron sp.
Family Actinodendronidae
updated Aug 10
Where seen? This large sea anemone is rarely encountered. Those seen were on sandy areas near coral rubble. The common name comes from its nasty sting, so please don't touch it!

Features: Diameter with tentacles expanded 15-20cm. About 40 fat fleshy tentacles with a thick base and tips covered with 'branches'. The oral disk has white stripes with small dark spots, radiating from the mouth. The animal can retract rapidly and completely into the ground when disturbed.

Sometimes mistaken for a flowery soft coral (Family Nephtheidae). While the soft corals don't sting, fire anemones do!

Kok Sheng shared a video clip of the sea anemone eating some fishes!
