A group of lizards is called a lounge. Only about 20 out of 6,000 lizards live in groups. Most lizard species are oviparous, meaning they lay their eggs. Many lizards lay their eggs in a secluded, thermally stable location, and then bury the eggs and leave them forever.
Some lizards do protect their eggs from predators. For example, five-lined skinks will curl around their eggs and watch them until they hatch. Long-tailed skinks are also very protective of their eggs, and will protect them from snakes if necessary. Once the young hatch, however, they quickly disperse and receive no parental care. A small number of lizards, called viviparous species, give birth to live young. These lizards may stay with their children for years.
