Marine Wildlife Encyclopedia Antarctic Anemone Urticinopsis
antarctica Like many other Antarctic marine animals, the
Antarctic anemone grows to a large size, but rather slowly. It
has long tentacles with powerful stinging cells and is capable
of catching and eating starfish, sea urchins, and jellyfish much
larger than itself. As there are often many Antarctic anemones
living close together, two or more may hold a large jellyfish.
As in most anemones, stinging cells on the tentacles fire barbed
threads into the prey to hold it and to paralyze or kill it.
