39. Day Gecko
Also known as Phelsuma, the day gecko is a small lizard found in Madagascar. These tiny reptiles are considered severely endangered and can be regarded as a threat to individual species. Unlike most geckos, these reptiles are active mostly during the day.
They have round pupils and a transparent plate covering their eyes. Day geckos use their tongues to clean their eyes and keep them moist. You can find day geckos in blue, green, and red colors. Many reptile enthusiasts keep day geckos as pets. They are small, reaching between 2 and 12 inches in length. Small day gecko species live around 10 years, but some in captivity can live for more than 20 years.
