Pectinia alcicornis
Pectinia alcicornis
Pectinia alcicornis is a stony coral in the family Merulinidae (order Scleractinia), recorded as Endangered and tied to Australia, Palau, and Japan.
The stony coral
It was first described by Saville-kent in 1871.
Merulinid corals include crispy, plated, and valley-forming colonies on Indo-Pacific reefs.
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
Pectinia alcicornis is recorded from Australia, Palau, Japan, Indonesia, Malaysia, and Philippines.
GBIF currently lists 274 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.
Habits
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.
The colony stays where it settled. Water quality, light, and a stable bottom decide whether tissue remains on the skeleton.
In crisis
CITES lists this taxon on Appendix II. Confirm the current appendix on the CITES checklist.
Warm-water bleaching, sedimentation, destructive fishing, and the curio trade sit behind many stony-coral badges. That is the group backdrop — confirm the official criteria for this name on the Red List.
Pectinia alcicornis 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.
