anemone Paraiptasia radiata Family Aiptasiidae updated Dec 2024 Where seen? This tiny anemone is sometimes seen stuck onto shells occupied by living snails such as whelks (Family Nassaridae). Sometimes also seen attached to tiny stones in silty sandy shores. They are more frequently encountered on our Northern shores, but also sometimes seen on other shores. Features: Diameter with tentacles extended 1-1.5cm. Tentacles many, long and thin, usually transparent with white bands. On the oral disk, often fine white stripes radiating from the mouth. Sometimes, a pair of tentacles are of a contrasting colour so that the anemone appears to have a moustache. Body column brown with pale stripes. Sometimes, a single single shell may bear two or three of these anemones. When full expanded, these anemone hitch-hikers may be bigger than the snail they are riding on! There are also small anemones that hitch a ride on a shell occupied by a hermit crab. Status and threats: As at 2024, it is assessed not to be approaching the criteria for being listed among the threatened animals in Singapore. |
