hermit-hitching anemone Calliactis sp. Family Hormathidae updated Jul 2024 Where seen? This rather large anemone is sometimes seen on shells occupied by hermit crabs on our Northern shores. The anemone is sometimes many times larger than the hermit crab! It is also seen attached to rocks and other small rubble, rubbish with a hard surface, as well as living snails. Features: Diameter with tentacles extended 2-3cm. Many short tapering tentacles. Some with opaque tentacles with dark base and paler tips, others with semi-transparent or beige tentacles with faint bands. Oral disk with radiating fine white stripes. Body column is thick, long with tiny bumps (verrucae) in regular bands. The body column usually covered with sediment. Small anemones are also seen on shells occupied by hermit crabs as well as on living snails. Status and threats: There is inadequate information as at 2024 to make an informed assesment of its conservation status in Singapore. |
