Halcampoides elongatus - Night Anemone

Range & Status

A relatively recently discovered species in the British Isles where it is only definitely

known from south-west and west Ireland, western Scotland, Isle of Man, Skomer and

the Channel Islands. Here it burrows amongst sand and gravel in depths of 10-25m, and seems to be entirely nocturnal in its habits. James (1983) reports a probable sighting of this species burrowing amongst maerl, comprised mainly of Phymatolithon calcareum with some Lithothamnion corallioides , in the Fal Estuary.
