In Mo'orea, French Polynesia, when corals were decimated by crown-of-thorns and a cyclone between 2007-2010, recruitment of six cryptic species of Pocillopora spp. primarily drove decadal reef recovery. Broadcast spawning for these genetically-verified species at Mo'orea is, however, undocumented in the scientific literature. We conducted in situ surveys over 58 days during September 2022-January 2023, October 2023-January 2024, and October 2024-December 2024. To identify the Pocillopora spp., we used molecular analysis of mtORF and PocHistone markers. P. meandrina and P. grandis spawned 2-3 days following the full moons of October-December. In contrast, P. verrucosa and P. tuahiniensis spawned at the new moons in November-December, with P. verrucosa spawning on lunar days 0-1, and P. tuahiniensis spawning on lunar days 1-3. Diel offset in the timing of spawning following sunrise was present in both moon phases indicating a temporal speciation barrier. P. verrucosa spawned ~45 minutes after sunrise, whereas P. tuahiniensis spawned ~73 minutes after sunrise. Similarly, P. grandis spawned ~40 minutes after sunrise, whereas P. meandrina spawned ~65 minutes after sunrise. Only one colony of P. effusa spawned (lunar day 3 new moon ~06:30-06:50), requiring further confirmation of the timing for this low abundance species. Collectively, these first spawning reports provide an initial scientific documentation of Pocillopora spawning at the genetically-verified species level in Mo'orea, increasing capacity to study the essential process of coral reproduction for critical reef building species.\n\ncdm_data_type = Other\nVARIABLES:\nSample_ID (unitless)\nDate_spawned (unitless)\nYear (unitless)\nMoon (unitless)\nMonth (unitless)\nDay_before_after_Moon (number of days)\nSpawning_Start_Time (unitless)\nSpawning_End_Time (hour:minute)\nHaplotype (unitless)\n...
