Lays up to 10+ (average 5 in Virgin Islands, 5-7 in Puerto Rico) clutches of 50-170 eggs (typically 70-90 normal eggs in the Atlantic, usually fewer than 60 in the eastern Pacific) at intervals of about 1-2 weeks; most individuals nest every 2-3 years. Nests at night, March-August in Western Hemisphere. Eggs hatch in 8-10 weeks. Reportedly sexually mature in 6-10 years, or possibly less, or perhaps 20-50 years; females in the Atlantic mature at a carapace length of 137-145 cm, Pacific females mature at slightly smaller size (Eckert 1992). Zug and Parham (1996) conducted a skeletochronological analysis and concluded that "for conservation management purposes, 9 years is a likely minimum age for maturity based on the youngest adult in the sample." Limited data indicate a post-maturation longevity of up to about two decades (Pritchard 1996).
