Flame shells

The Flame shell is a particularly amazing species, building nests using byssus threads which knit the seabed together forming a reef sometimes many hectares in size. While the bright orange tentacle mollusc is on its own a very incredible wee creature, what it builds becomes home to 100's of other species.
