Agama Lizard

Agama lizards are sometimes called rainbow lizards because of the colorful displays put on by the dominant males. While most agamas are green and brown, dominant males show off by rapidly turning their bodies blue and their heads bright red or yellow. Most agamas live in small groups with the dominant male ruling over several females and sub-males. While sunning themselves each morning, the dominant male will claim the most elevated spot, with subordinates in lower areas. Agamas hunt by vision and prefer to wait for an insect to come by. Their sticky tongues help them hold onto prey.
Females reach sexual maturity at age fourteen to eighteen months, males at two years. A. agama reproduces during the wet season although they are capable of reproducing nearly year round in areas of consistant rainfall(Porter et al. 1983). The male will approach the female from behind and head bob to her. If she accepts then she will arch her back with her tail and head raised. The male walks to her side and grasps her neck and puts his leg on the female's back, the pair swivel 90 degrees in order to bring their cloacas together and thrusts his tail onto her cloaca inserting his right or left hemipenes (depending on side location). This mating ritual usually lasts one to two minutes when the female will scurry away and the male also after several minutes (Harris 1964).
The female lays her eggs in a hole she digs with her snout and claws. The hole is five centimeters deep and is found in sandy, wet, damp soil that is exposed to sunlight nearly all day and covered by herbage or grasses. The eggs are usually laid in clutches ranging from five to seven ellipsoidal eggs. A. agama is a thermoregulated embryo species resulting in all males at twenty-nine degrees Celsius and all females at twenty-six to twenty-seven degrees Celsius (Crews et al. 1983).
