Sarcophyton elegans is an Indo‑Pacific leather (toadstool) soft coral in family Alcyoniidae. Colonies have a stout stalk and a flat to cup‑shaped disc densely covered by retractile polyps. It hosts Symbiodiniaceae, deriving most energy from photosynthesis and supplementing with suspended particulates.
Ecology & Biology
Nutrition: photosymbiosis plus capture of micro‑zooplankton/POC.
Reproduction: sexual spawning/planulation and asexual fission/fragmentation; widely aquacultured by fragging.
Self‑cleaning: periodic sloughing of the outer layer to shed films/sediments; temporary closure is normal.
Identification
Mushroom‑like silhouette with slightly upturned disc margins; colours often golden‑yellow, cream, beige. Compared with S. glaucum, S. elegans tends to show brighter yellow tones and a more even disc; definitive ID may require sclerite microscopy.
Colony size & Longevity
Disc diameter: typically 10–30 cm; up to 40–60+ cm.
Height: ~8–30 cm.
Life: long‑lived on stable reefs; multi‑year to decades.
Range & Habitat
Tropical Indo‑Pacific reefs—reef flats, lagoons and upper outer‑reef slopes (≈1–25 m) with moderate flow to clear sediments.
Threats & Conservation
Stressors: warming/bleaching, sedimentation/turbidity, pollution, severe storms.
Trade: aquarium collection may affect local stocks; ex situ aquaculture reduces wild harvest needs.
IUCN: generally Not Evaluated (NE) at species level; protection via MPAs, water‑quality control and sustainable trade.
