Calotes Angleheads Dragon Lizards and Relatives: Agamidae
Behavior And Reproduction
Agamids are diurnal (die-UR-nuhl), or active during the day. They spend a lot of time basking, or resting, in the sun. Some species prefer to sun themselves on flat rocky areas, while others like to climb onto tree trunks or shrubs to sunbathe. If the desert species get too hot, they go into cooler underground burrows, or holes, to rest.
Agamids have different ways of protecting themselves against predators. The bearded dragon lizard, for example, has spiny body scales. Some agamids run underground or into a rock crevice (KREH-vuhs), or crack. The Dabb spiny-tailed lizard runs into its burrow and lets the spiny part of its long, thick tail hang out. If the predator keeps pestering it, the lizard swishes its tail from side to side, which discourages most predators.
Agamid males typically are very territorial, meaning that they are protective of their living areas. A male agamid mates with females inside his territory, where several females may live. When challenging other males for a mate, an agamid may bob its head, push up on rocks to make it look bigger, open and close its mouth, and enlarge its dewlap, the expandable flap under the chin. Some males become brightly colored during courtship. The Indian bloodsucker agamid expands the dewlap during courtship, and its head and throat turn bright red. That color gives the "bloodsucker" its name.
Most agamid females lay soft-shelled eggs after mating. The smaller agamid species lay a small number of eggs. The larger species may lay up to two dozen eggs. There may be one egg clutch, or group, per season or several throughout the year. Eggs are usually buried in damp soil or in leaf litter. There are some agamid species, such as the toad-headed lizards, that give birth to live young.
