Viewed from a distance jewel anemones appear as a patches of colour spread across submerged rock faces. Closer inspection shows that the colour comes from what appear to be numerous individual anemones. Each anemone is actually linked by slivers of tissue to others of the same colour and hence the same clone group and have expanded out to form a colony. Other colonies nearby will each belong to a different clone group and hence will exhibit different colours. Neighbouring colonies compete with each other for space. To 10 mm.
