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.
Acropora grandis is a colonial species of staghorn coral that can grow into a large clump as much as 7 metres (23 ft) across. In shallow water it tends to grow as a prostrate, 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. [3] The polyps usually have twelve tentacles, one of which is elongated, and are connected together inside the skeleton by a maze of interconnecting channels. [4]
Acropora grandis is found in shallow water in the western Indo-Pacific. Its range includes Madagascar, Mozambique, the Red Sea, Mauritius, Malaysia, Indonesia, New Guinea and the Great Barrier Reef. It grows in various reef locations but is more common on the upper slopes and in lagoons. [3] The depth range is 5 to 15 metres (16 to 49 ft) and it favours a well-lit site with a strong current. [5]
Acropora grandis is a zooxanthellate species of coral. [2] This means that it has symbiotic dinoflagellates living within its tissues. These photosynthetic microalgae, combined with pigments in the tissue, are responsible for the colour of the colony and provide a proportion of its nutritional needs. [4]
Acropora grandis liberates its gametes into the sea where fertilisation takes place. Synchronised spawning takes place, and in the part of its range in the Northern Hemisphere, this is four or five days after the full moon. The larvae are planktonic and drift with the currents before settling on the seabed to start a new colony. [4]
When fragments of Acropora grandis were planted into a mid-water nursery bed, over 95% survived and these were later transplanted onto a reef at Phi Phi Islands, Thailand that had been devastated by the 2004 Indian Ocean Tsunami. [6] This was successful and showed that damaged reefs can be regenerated with the help of fast-growing corals. [6]
Acropora prolifera, the fused staghorn coral, is a branching, colonial, stony coral found in shallow parts of the Caribbean Sea, the Bahamas and southern Florida.
Acropora secale is a species of branching staghorn stony coral. It is found in shallow parts of the Indo-Pacific Ocean and the type locality is Sri Lanka. The oldest fossils found date back to the Pleistocene.

Isopora palifera is a species of stony coral in the family Acroporidae. It is a reef building coral living in shallow water and adopts different forms depending on the water conditions where it is situated. It is found in the Western Indo-Pacific Ocean as far east as Australia.
Acropora loripes is a species of branching colonial stony coral. It is common on reefs, upper reef slopes and reef flats in the tropical Indo-Pacific. Its type locality is the Great Barrier Reef.
Acropora millepora is a species of branching stony coral native to the western Indo-Pacific where it is found in shallow water from the east coast of Africa to the coasts of Japan and Australia.
Acropora nasuta is a species of branching stony coral in the family Acroporidae. It is native to the western and central Indo-Pacific where it is found in shallow reef habitats. Like other corals of the genus Acropora, it is susceptible to coral bleaching and coral diseases and the IUCN has listed it as being "Near Threatened".
Acropora abrotanoides is a species of acroporid coral found in Indo-Pacific waters from the Red Sea and the Gulf of Aden east to the East China Sea, Japan, the central Pacific Ocean and Australia. It is found in shallow coral reefs that are exposed to the action of strong waves, at depths up to 15 m. It is vulnerable to coral bleaching, disease and crown-of-thorns starfish. It is resistant to predation as it has well-developed radial corallite lips.
Acropora muricata, commonly called staghorn coral, is a species of acroporid coral found in the Gulf of Aden, the Red Sea, Indian Ocean, Persian Gulf, Australia, central Indo-Pacific, Japan, Southeast Asia, the East China Sea and the oceanic central and western Pacific Ocean. It is found in tropical shallow reefs, slopes of reefs, and in lagoons, from depths of 5 to 30 m. It was described by Dana in 1846.
