Acropora striata

Acropora striata is a stony coral in the family Acroporidae, building branching skeletal structures composed of calcium carbonate secreted by its colonial polyps. Like other Acropora species, it hosts symbiotic zooxanthellae algae within its tissues, which supply the coral with nutrients through photosynthesis while giving the colony its characteristic coloration. Its branching growth form creates complex three-dimensional structure on the reef, providing shelter and habitat for fish, invertebrates, and other reef-associated organisms, making it an important contributor to overall reef architecture and biodiversity.

This species occurs across the Indo-Pacific region, with recorded populations in Australia, Japan, China, Thailand, India, the Maldives, Seychelles, Mauritius, Mayotte, and numerous Pacific island nations including Fiji, Palau, Kiribati, the Marshall Islands, the Solomon Islands, and the Cook Islands. It inhabits rocky substrates in marine neritic (shallow coastal) waters, typically on reef structures where light penetration supports its symbiotic algae.

The species faces multiple concurrent pressures, including fishing and harvesting activities, recreational use of reef areas, and disease outbreaks linked to both invasive and native species. Water quality degradation from domestic wastewater, agricultural runoff, and non-timber crop cultivation contributes to coral stress, while broader habitat alteration and unspecified pollution sources compound these effects. These threats operate against a backdrop of ocean warming and acidification affecting Acropora corals broadly.

Conservation responses include marine protected area designations across parts of its range, reef monitoring programs, and international trade regulation under CITES, which lists all Acropora species. Restoration efforts using coral fragmentation and transplantation are underway in several countries. Population trends remain in decline, and the species is currently assessed as Endangered, with its long-term outlook dependent on reductions in local stressors and broader climate mitigation.
