Striped
sand anemone
Paracondylactis hertwigi
Family Actiniidae
updated Dec 2024
Where
seen? This small anemone is often seen on our Northern
shores, on soft silty sand near seagrasses.
Features: Diameter with tentacles 3-4cm. It has about 40 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 has a pattern of radiating
stripes and white bars. The edge of the mouth has dark-and-light bars. Body column smooth without large bumps (verrucae), although there are a few bumps near the oral disk.
Status and threats: As at 2024, it is assessed not to be approaching the criteria for being listed among the threatened animals in Singapore.
