Conservation overview

Staghorn coral is a fast-growing branching coral that once built much of the structure of Caribbean reefs. It is assessed as Critically Endangered.

Corals are colonial animals, not plants: each branch is constructed by tiny polyps living in partnership with symbiotic algae.

Range & habitat

A fast-growing branching coral of Caribbean and western Atlantic reefs.

Major threats

Threats below are drawn from the authoritative sources listed on this page. For the current, complete assessment, see the IUCN Red List.

  • Ocean warming and coral bleaching
  • Coral disease
  • Ocean acidification and storm damage

Why it matters

Branching corals like staghorn create the three-dimensional habitat that reef fish and other animals depend on, so their loss reshapes entire reef communities.
