Abstract

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 ( 1.6 and >4.0 times slower, respectively, compared with those of Peachia hastata from Scotland, recorded at similar to 11-14 degrees C. Q(10) values calculated from these data are in the range 1.4-3.0, and thus provide little evidence supporting any evolutionary acclimation of the processes involved in burrowing has occurred in Halcampoides from the Antarctic, although the data are limited.
