Correct name concerning WoRMS: Liponema brevicorne (McMurrich, 1893)
Correct name concerning Sealifebase: Liponema brevicornis (McMurrich, 1893)
Recorded from Kenmare River and Kilkieran Bay (western Ireland) and from sea-lochs on the western coast of Scotland, notably Lochs Duich and Fynne.
Lives in a long thick tube, often over 1 m long, in mud or muddy sand, from about 10-130 m depth. Found only in very sheltered conditions around the head of fijordic sea lochs.
Pachycerianthus multiplicatus is a large burrowing anemone, occupying a tube-like burrow that may exceed 1 m in length. Both the length of the column and the breadth of the tentacles can reach 30 cm. The tentacles are long and occur in two cycles, with up to 200 tentacles in the marginal cycle. The tentacles are incapable of retraction but may coil spirally on disturbance. The colour of the inner tentacles is pale buff or chestnut and the marginal tentacles are whitish with fine brown bands, or plain white.
Column relatively stout, usually broadest distally, provided with an aboral pore.
Marginal tentacles arranged in four pseudocycles, up to about 200, very long, even in contraction much longer than disc diameter.
Attains a very large size, reaching 30 cm in height and, including the tentacles, in width.
Pachycerianthus multiplicatus is similar to Cerianthus lloydii, but is much longer and has a broader column.
A pom-pom anemone takes on a variety of shapes—from low and flat to round and puffy. In fact, scientists have seen puffed up anemones rolling across the seafloor like living tumbleweeds, "blown" by deep sea currents. Scientists aren't sure why pom-pom anemones change shape and roll around—they might be looking for "greener pastures," where there's more food to eat.
Anything that finds its way into the ocean, whether it's tossed away as trash, washes off a beach or falls off a boat, may eventually make its way to the deep sea. It's important to realize that the deep sea is not so far away that it's beyond the reach of human activities. Living creatures in the deep are affected by what we do at the surface.
A pom-pom anemone's stinging tentacles capture crustaceans and krill swimming by.
