  1. Modelled age (days) to settlement competency, where the cohort is more likely than not (TC50) to have exceeded a 30% settlement threshold, for 21 coral species. The cue (i.e. CCA, rubble or disc) that provided the earliest TC50 estimate at a 30% threshold is identified. Upper and lower credible intervals (CI) around the TC50 estimates are presented. Precompetency periods are ranked by short (<3 days), mid (3–5 days), and long (>5 days) duration. CCA = Crustose coralline algae from the Porolithon spp. complex.*reference for oocyte diameter is C.J. Randall, personal observation.
