Where
seen? This anemone is sometimes seen in small groups on
coral rubble on our Northern and Southern shores. On Pulau Sekudu, they are sometimes seen in large numbers
carpeting the ground. Elsewhere, they are seen alone or in smaller
numbers.
Features: Diameter with tentacles
extended 3-4cm. Many short tentacles reddish brown, paler at the base.
Tentacle tips may be slightly bulbous. Oral disk large relative to
the tentacles, same colour as tentacles. Body column smooth and pale.
Isactinia citrina can also look like Neon anemones.
Status and threats: As at 2024, it is assessed not to be approaching the criteria for being listed among the threatened animals in Singapore. |
