A lounge is a collection of lizards. Out of 6,000 lizards, only roughly 20 dwell in groups. The majority of lizard species are oviparous, which means they lay eggs. Many lizards lay their eggs in a remote, thermally stable area, bury the eggs, and then leave the eggs there indefinitely.

Some lizard species do defend their eggs from scavengers. Five-lined skinks, as an illustration, will huddle over their eggs and watch them until they hatch. The eggs are also fiercely guarded by long-tailed skinks, who will defend them against snakes if required. But as soon as they hatch, the young scatter and are abandoned by their parents. Only a few kinds of lizards, known as viviparous species, deliver live young. These lizards may spend many years with their young.
