Striped
bead anemone
Paracondylactis singaporensis
Family Actiniidae
updated Dec 2024
Where
seen? This small anemone is commonly seen especially
on our Northern shores. Even relatively "beat up" shores
with few other lifeforms will have these anemones. It is often
found in small clusters of a few individuals. It settles wedged in
crevices on rocks, on hard surfaces such as jetty pilings, boulders,
rocks, and on small stones on the shores. When exposed at low tide,
it tucks its tentacles into its body and looks like a blob.
Features: Diameter with tentacles 2-3cm. Many semi-transparent tentacles that
taper to a pointed tip. On the upper side of the tentacles, there
is a pattern of white bars across a pair of dark parallel lines that
run the length of each tentacle. The oral disk may be plain or have
a pattern of stripes radiating out from the mouth.
Sometimes mistaken for the Banded bead anemone,
which is smaller than the Striped bead anemone. The Banded bead anemone is found in tight clusters of many individuals, while the Striped bead anemone may be seen alone or in loose clusters of a few individuals.
Status and threats: There is inadequate information as at 2024 to make an informed assesment of its conservation status in Singapore.
