Burrowing in the Antarctic anemone, Halcampoides sp., from Signy Island, Antarctica
Antarctic anemones of the genus Halcampoides inhabit low intertidal and shallow subtidal zones. They readily burrow into soft sediments following disturbance. The process of re-burying was recorded using time-lapse video in the aquarium of the British Antarctic Survey with specimens of a species col...

Antarctic anemones of the genus Halcampoides inhabit low intertidal and shallow subtidal zones. They readily burrow into soft sediments following disturbance. The process of re-burying was recorded using time-lapse video in the aquarium of the British Antarctic Survey with specimens of a species collected from the shallow sublittoral (<1 m depth) at Signy Island. Penetration of the sediment takes place by a similar mechanism to that employed by burrowing anemones such as Peachia hastata from lower latitudes. Penetration initially is brought about by peristaltic contractions that involve only the modified base, or physa.
