Abstract Antipathes galapagensis is a prevalent habitat-forming black coral in subtidal ecosystems of the Galápagos Marine Reserve (GMR). Despite their ecological importance and status as CITES-regulated order, little known about depth distribution, population structure ecology GMR. Surveys were conducted 2021 2022 at 9 sites central Archipelago to investigate how densities, occupancy, size, habitat utilization, epizoan overgrowth varied between 2.0 20.0 m depth. The shallowest corals occurred 3.4 depth, one occurrences an spp. world. Coral density increased with maximum 5.2 colonies per 2 observed across range surveyed.
