Critically Endangered
Pillar coral
Dendrogyra cylindrus
Pillar coral is a hard coral (order Scleractinia) found in the western Atlantic Ocean and the Caribbean Sea.
Appearance
This coral is usually some shade of beige or brown.
This coral can grow to a height of 3 m (10 ft) with pillars more than 10 cm (4 in) wide but is usually much smaller than this.
Range and habitat
Pillar corals are found in the warmer parts of the western Atlantic Ocean and the Caribbean Sea. Within its range, D. Cylindrus is common in some places, but rare in other seemingly suitable locations. Some of the islands in the Bahamas have plentiful numbers of colonies as does the north coast of Jamaica.
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.
Pillar coral is Critically Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
