Introduction

The common Jewel Anemone lives on rocks and coastal structures such as piers in shaded, wave-exposed areas.

Identification

The tentacles of the anemone-like polyps of the Jewel Anemone have a small round ball at the tip that is usually more brightly coloured than the rest of the polyp, resembling a jewel.

Habitat

The Jewel Anemone is found in coastal waters, on rocky reefs and shores.

Distribution

The Jewel Anemone is found in south-eastern Australia.

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.
