Astreopora cucullata

The stony coral

It was first described by Lamberts in 1980.

Acroporid corals are reef-builders. The animal is a colony of polyps sharing one calcium-carbonate skeleton, usually with photosynthetic algae in the tissue.

Stony corals secrete a hard calcium-carbonate skeleton. A named ‘species’ on a reef is a colony of polyps, often hosting zooxanthellae that need sunlit, relatively clear water.

Range and habitat

Astreopora cucullata is recorded from American Samoa, Australia, New Caledonia, Japan, Indonesia, and Papua New Guinea.

GBIF currently lists 116 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.

Astreopora cucullata 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.
