Where it lives

Florida, the Bahamas, and the Caribbean

Ranges stay general on purpose. Witness never publishes a location that could help someone find an animal already under pressure.

What threatens it

  • Warming & bleaching
  • White band disease
  • Ocean acidification
  • Land-based pollution

Life cycle

Once a year, after the late-summer full moon, colonies broadcast eggs and sperm into the water in synchrony. The rest of the year, reproduction is a matter of breakage — fragments that land well become new colonies.

Field notes

Every passage carries the number of the source it came from. Nothing here is written from memory.

Staghorn coral is an animal — one animal made of thousands: identical polyps growing together into antlered branches.Source 1

It runs on a partnership: photosynthetic algae live inside its cells and feed it by day, while tentacled polyps snatch plankton.Source 1

Healthy, it grows up to eight inches of new branch a year, and its thickets are habitat for reef fish.Source 1

These corals built the Caribbean's reefs over the past five thousand years, and their thickets blunt storm waves before shorelines.Source 1

Then, beginning in the 1980s, white band disease erased 97 percent of it.Source 1

The remaining danger is heat: too-warm water makes coral expel its algae, bleaching white and starving.Source 2

But a broken branch is not an ending — fragments that reattach grow into whole new colonies.Source 1

Restoration runs on that fact: divers hang finger-sized fragments from underwater coral trees, and in six to nine months each is reef-ready.Source 3

Once a year, after the late-summer full moon, whole reefs spawn in synchrony — and outplanted staghorn at Molasses Reef became the first restored corals documented joining in.Source 1Source 4

To witness the staghorn is to count the reef itself as a creature that can be replanted.Source 5

Did you know

The world's largest in-ocean coral nursery — 1.5 acres off Tavernier, Florida — can grow more than 50,000 reef-ready corals a year on underwater trees.
