Agama agama: The Common Agama

The common agama, scientifically known as Agama agama and often referred to as the red-headed rock agama, is a highly adaptable lizard species found across much of sub-Saharan Africa. Its range has also expanded to include parts of Florida due to introduction via the reptile trade. This species is notable for its striking sexual dimorphism and territorial behavior.

Description and Identification

Common agamas typically range from 13 to 30 cm in total length, with males generally being larger than females. A key distinguishing feature is the coloration: dominant males display a vibrant blue body and a yellow tail, while females, juveniles, and subordinate males sport an olive green head. Their underside is white, and their hind limbs are brown, with a characteristic light stripe running down the middle of the tail, often marked by dark patches.

Habitat and Distribution

Native to a vast array of African nations from Benin to Uganda, the common agama thrives in arid conditions and is well-adapted to its environment. While its natural habitat includes various landscapes, it has also become common in urban settings. The species has successfully established itself in southern Florida, demonstrating its resilience and adaptability to new environments.

Behavior and Social Structure

These lizards are diurnal, remaining active throughout the day but seeking refuge from extreme heat during the hottest hours. Male common agamas are highly territorial and engage in frequent disputes to establish and defend their space. They live in social groups, typically comprising a dominant male (the 'cock'), several females, and subordinate males. The territory of a dominant male is often centered around a prominent landmark such as a tree or boulder.

Diet

The common agama is primarily an insectivore, consuming a variety of insects including ants, grasshoppers, beetles, and termites. Their diet is versatile, however, and can also include small mammals, other reptiles, and plant matter such as flowers, grasses, and fruits. They are adept hunters, using their sticky, mucus-covered tongues to capture smaller prey.

Reproduction

Reproduction in Agama agama usually occurs during the wet season, though they can reproduce in areas with consistent rainfall. Females reach sexual maturity around 14-18 months, while males mature at two years. After fertilization, the female digs a hole in damp, sandy soil to lay a clutch of 5-7 ellipsoidal eggs, which typically hatch within 8 to 10 weeks. A fascinating aspect of their reproduction is temperature-dependent sex determination, where different incubation temperatures result in male or female offspring.
