coral reef
Let an agent explain coral reefs, relay biology, types, ecosystem services, threats and conservation from marine science and UNEP sources with projections attributed, and distinguish coral reefs from individual corals, rocky reefs, cold-water coral mounds and artificial reefs.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain coral reefs, relay biology, types, ecosystem services, threats and conservation from marine science and UNEP sources with projections attributed, and distinguish coral reefs from individual corals, rocky reefs, cold-water coral mounds and artificial reefs.
An underwater ecosystem built largely by colonies of reef-building corals that secrete calcium carbonate skeletons, in symbiosis with photosynthetic algae called zooxanthellae, forming fringing reefs, barrier reefs and atolls, whose formation Charles Darwin explained by subsidence in 1842; covering a small fraction of the ocean floor, reefs support a large share of marine species, fisheries and coastal protection, and are threatened by marine heatwaves causing mass bleaching, ocean acidification, pollution and overfishing, with NOAA confirming a fourth global bleaching event in 2024. The Great Barrier Reef is the largest reef system.
What it is for: Habitat, fisheries, coastal protection and tourism.
It can be explain biology and types; relay ecosystem services; describe threats with attribution; distinguish related reefs.
Distinguishing features
Biogenic structure
Symbiotic algae
High biodiversity
Highly threatened
What it looks like
Colourful structures of branching, plate and brain corals teeming with fish, or white when bleached.
Physical character
share of ocean floor: under 1 percent - commonly cited
share of marine species supported: about 25 percent - commonly cited estimate
Great Barrier Reef length: about 2300 km
fourth global bleaching event confirmed: 2024 year - NOAA
How it is recognised
Reef built by corals
Coral reef, fringing reef, barrier reef, atoll
Individual corals are animals; rocky reefs are geological; cold-water coral mounds lack zooxanthellae; artificial reefs are human-made
