''Acropora grandis'' is a species of colonial stony coral. It is a large species with multiple branches forming a bush-like structure and is found on reefs and in lagoons. It is native to the tropical western Indo-Pacific and has a range extending from East Africa to the east coast of Australia. ==Description==
''Acropora grandis'' is a colonial species of staghorn coral that can grow into a large clump as much as across. In shallow water it tends to grow as a prostate, tangled bush with thick branches but in deeper water it has a more upright and open structure. The radial corallites are varied in shape and size and those near the tips of the branches are tubular and elongated. The general colour is usually reddish-brown but can be various shades of blue, green or purple. The branch tips are a paler colour, have multiple axial corallites and are fragile and easily damaged. The polyps usually have twelve tentacles, one of which is elongated, and are connected together inside the skeleton by a maze of interconnecting channels.〔
