The little worms create beautiful colonies that are also known as 'Sydney coral.'
Tiny creatures make some incredible tiny homes – think of wasp nests and ant hills, or in the case of worms, the incredible colonies created by the encrusting galeolaria, like the ones pictured here in Tinderbox, Tasmania. Photographer John Turnbull writes:
Galeolaria is a very common encrusting worm which builds huge colonies on rocks and pylons. Up close you can see the little grey trapdoor which the worm uses to seal its tube when the tide is out.
A very different kind of curb appeal...
