Other behaviours and adaptations

Often large colonies of Jewel Anemones cover the walls of underwater caves, with sheets of polyps connected by a single base. The edge of a colony is usually clearly defined as adjoining colonies are often a different colour. Cave walls can be a spectacular patchwork of different colours as colonies compete with each other for space.
