All about the Giant Madagascar Day Gecko

Giant Madagascar Day Geckoes are considered to be one of the largest species of day Geckoes. They are iridescent green in color with a red marking on the head and red dots on their torso. They also sport a tapering red line that runs from their nostrils to their eyes. Their underbelly is cream to pale yellow in color. Their heads and bodies are bright green to turquoise in color. Their eyes are encircled with black. They have unique feet that have their undersurface lined with lamellae, a thin-plate tissue. Lamellae help day geckoes walk vertically and inverted on smooth surfaces such as glass. Lamellae also help geckoes in respiration.

Males and females look different from one another (sexually dimorphic). Males have distinguishable sex organs in their anal area. Females have chalk sacs on either side of their necks in which they store calcium that they use to build their eggs. They are 10 inches in length and they are very light (50 to 70 grams in weight).

Diet/ Habitat/ Range

Standings Day Geckoes are native to and only found in Madagascar living in dry forests and thornbrush. They are omnivores feeding on insects, other invertebrates, fruits, pollen, and nectar.

Behavior

Standings Day Geckoes are active during the day (diurnal) and live in trees (arboreal). Unlike mammals, geckoes cannot thermoregulate. They are often seen basking in the sun to warm up. Their body color helps them hide from predators in their natural habitat (camouflage). Males are highly territorial and they will fight with other males to protect their food resources and their females. Uniquely, it has been observed that females tend to display territorial displays against other females, an uncommon behavior for female geckoes.

Reproduction

Female Standings Day Geckoes lay eggs that hatch in two months. They sexually mature at one year of age.
