About Madagascan giant day gecko
What is it?
The Madagascan giant day gecko, scientifically known as Phelsuma grandis, is a striking species of diurnal, arboreal gecko native to the tropical and subtropical forests of northern Madagascar. It is the largest species within the Phelsuma genus, which comprises over 70 species and subspecies. Due to their size and vibrant appearance, they are also commonly referred to as the Madagascar giant day gecko or simply the Giant Day Gecko.
Physical Characteristics
This impressive lizard typically reaches a total length of 23 to 28 centimeters (9 to 11 inches), with females generally being smaller than males. Its body is a brilliant green, though rare individuals may exhibit a bluish-green hue. A prominent red stripe runs from the nostril to the eye, and the back is usually marked with red dots or bars, though these markings can vary significantly and even be absent in some individuals. Young geckos often display more intense red coloration than adults, which tends to fade as they mature.
Habitat and Distribution
Phelsuma grandis is widely distributed across northern and northwestern Madagascar. The species has also been introduced to several other subtropical regions, including Florida, Hawaii, and Reunion Island. In Mauritius, where it was introduced in the mid-1990s, it has spread extensively and is considered a potential threat to native biodiversity by encroaching on the habitats of other day gecko species.
Diet and Behavior
As an omnivorous species, the Madagascan giant day gecko feeds on a variety of insects and other invertebrates, occasionally supplementing its diet with very small vertebrates. They also have a fondness for soft, sweet fruits, pollen, and nectar, showing a preference for red or yellow colored nectars. These geckos are territorial, particularly the males, who will defend their space against other males. They are known for their speed when startled and their adeptness at escaping enclosures. Lacking eyelids, they keep their eyes clean by frequently licking them.
Reproduction
The breeding season for Phelsuma grandis typically occurs between December and June. During this period, females are capable of laying multiple pairs of eggs. The incubation period for these eggs varies, generally lasting between 48 and 80 days, with temperature playing a significant role in the hatching time. Cannibalism of their own young has been observed in both wild and captive populations.
