Endangered
Acropora nana
Acropora nana
Acropora nana was first described by Théophile Rudolphe Studer in 1879.
The staghorn coral
It was first described by Théophile Rudolphe Studer in 1879.
Acropora colonies are the staghorns and tables of warm reefs: branching or plate-like skeletons that can add tissue quickly when the water stays clear, bright, and stable.
Acroporid corals are reef-builders. The animal is a colony of polyps sharing one calcium-carbonate skeleton, usually with photosynthetic algae in the tissue.
Range and habitat
Acropora nana is recorded from American Samoa, Australia, Japan, Indonesia, Papua New Guinea, and Marshall Islands.
GBIF currently lists 667 occurrence points. Those points follow where people logged the taxon — museum drawers and surveys included — not a closed range boundary.
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 nana 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.
