Montipora confusa

Montipora confusa is a colonial reef-building coral in the family Acroporidae, forming encrusting to plate-like or laminar colonies typical of the genus. Like other Montipora species, its polyps are small and it relies on symbiotic zooxanthellae for the majority of its energy needs, contributing calcium carbonate skeletal structure to reef frameworks and providing microhabitat for reef-associated invertebrates and fish.

The species occurs in the western Pacific and parts of Southeast Asia, with records from Papua New Guinea, the Solomon Islands, Australia, Malaysia, Vietnam, China, and Fiji. It inhabits marine neritic (shallow coastal) waters, typically on reef slopes and flats within the photic zone required by its symbiotic algae.

Montipora confusa is classified as Endangered, with a decreasing population trend. Threats include harvesting for the aquarium and curio trade, damage from recreational activities such as diving and anchoring, disease outbreaks and pressure from problematic native species (such as coral predators), and water quality degradation from domestic and urban wastewater, agricultural runoff, and other pollution sources. Habitat shifting and alteration, linked to broader environmental change, compounds these pressures across its range.

Conservation measures affecting this species are largely indirect, arising from marine protected areas and reef management programs across its range countries, together with international trade regulation under CITES Appendix II, which covers stony corals including Montipora. Water quality improvement initiatives and fisheries management in some jurisdictions also provide partial protection.

Given the combination of localized extraction pressure, chronic pollution inputs, and disease, the species' outlook remains unfavorable, with continued population decline expected unless threats are substantially reduced across its geographic range.
