Acropora grandis
Acropora grandis
Acropora grandis is a staghorn coral in the family Acroporidae (order Scleractinia), recorded as Endangered.
Appearance
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.
Range and habitat
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.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Diet
By day the polyps sit in sunlit water and feed the algae in their tissue; at night they can catch plankton. A colony does not walk. It lives or dies on that patch of reef.
A stony-coral colony is fixed. Growth, bleaching, and death happen in place. Collection and gear damage remove the skeleton as well as the tissue.
In crisis
CITES lists this taxon on Appendix II. Confirm the current appendix on the CITES checklist.
Branching acroporids are among the first corals to bleach in a marine heatwave and among the first to smash in a storm or under an anchor.
Acropora grandis is Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
