In West Indies, most nesting occurs May-November (apparent peak May-June). Individual adult females lay 3-6 (averaging 3-5, depending on location) clutches of 50-200+ eggs at night at intervals averaging 14-18.5 days; adult females nest at interval of usually 2 to several years (mean as low as 1.84 years in Malaysia, 5-7 years in the Solomon Islands) (see NMFS and USFWS 2007). Eggs hatch in about 2 months. Age of sexual maturity is roughly 20-40 years (ranges from 20+ years in the Caribbean to at least 30-35 years in the Indo-Pacific to 31-38 years in Australia) (see NMFS and USFWS 2007). Formerly nesting concentrations likely were larger than they they cuurently are in most areas; now nesting generally is distributed at low densities in the Caribbean (small nesting concentrations may occur on Antigua), but up to 100 per night may nest on some islands in northern Australia (see Van Meter 1983); nesting aggregations also occur in Oman, Yucatan, and the Sychelles, and these may be typical of pre-exploitation nesting densities (see NMFS and USFWS 2007).
