Claim a nest, get no rest. The female Allen Cays iguana needs lots of energy to bring the next generation into the world, which is why she takes longer than any lizard to reach sexual maturity-at least 12 years. She defends her nesting site with head bobs, charges and face-offs with other iguanas. Then she digs a nesting chamber, lays her eggs, and partially buries them. Hatchlings dig themselves out 80 to 85 days later. Those that survive become of some of the largest-and most endangered-lizards in the world. Constrained by its habitat and harried by human interference, including capture for pet trade, the iguana can hardly rest easy.
