Do iguanas lay eggs or give birth?

Females lay their eggs about 65 days after mating (eggs take 59 to 84 days to develop before they are laid). Over the course of three days, females may up to 65 eggs, each measuring around 15.4 mm in diameter, and 35 to 40 mm in length (Frye, 1995). Eggs are deposited into nests which are located 45 cm to more than a meter deep, and may be shared with other females if nesting areas are limited.
