About Giant Day Geckos

Day geckos are diurnal and live in trees. In the genus Phelsuma, the giant day gecko is the largest species, as the name would suggest. When fully grown they can be about one foot in length.

Besides, red markings, they may also have small blue spots on their body. They are usually bright green but can be a bluish-green color as well. When they get stressed they become dark green and their red marks become more orange. The geckos bright colors help to camouflage them, making it easier for them to hunt prey.

They make a call by clicking their tongue against the roof of their mouth. The sound produced by this motion sounds similar to a frog.
