Uroplatus phantasticus, the satanic leaf-tailed gecko, eyelash leaf-tailed gecko or the phantastic leaf-tailed gecko, is a species of gecko indigenous to the island of Madagascar. First described in 1888 by George Albert Boulenger, U. phantasticus is the smallest in body of the Uroplatus geckos, though there is an ongoing debate as to whether one of its cousins, U. ebenaui, is smaller because of its shorter tail. Etymology The generic name, Uroplatus, is a Latinization of two Greek words: "ourá" (οὐρά) meaning "tail" and "platys" (πλατύς) meaning "flat". Its specific name phantasticus is the Latin word for "imaginary", based upon the gecko's unique appearance, which led Belgian naturalist George Albert Boulenger to describe it as “mythical” in 1888. Distribution and habitat The species is endemic to Madagascar, meaning it is found nowhere else. It is an arboreal species that relies on its natural camouflage in the northern and central tropical forests of Madagascar. Description Its adult size is up to 90mm in total length, including the tail. As with all Uroplatus geckos the tail is flattened, but the leaf-like appearance is only seen in the ebenaui complex (U. phantasticus, U. ebenaui, and U. malama; although the tail size is much reduced in U. ebenaui). It has often been debated whether U. phantasticus is in fact the same species as U. ebenaui (the Nosy Bé flat-tailed gecko). However U. phantasticus possesses more, and longer, spines on the head, body and trunk. Other members of the genus Uroplatus have flattened tails that serve more to diminish the profile of the gecko while it is inactive. Some U. phantasticus geckos even have notches in their tails to further mimic a decaying leaf. This is also thought to be a form of sexual dimorphism, as the trait seems more common in the males of the species. In addition, U. phantasticus has an eyelash-like projection above each eye. During daylight hours, these adaptations help the gecko blend into its surroundings. At night it helps the gecko hunt for prey by providing camouflage. Geckos possess no eyelids, just a transparent covering over their eyes, and so they use their long, mobile tongues to wipe away any dust or debris that gets into the eye. The gecko occurs in a variety of colors, including hues of purple, orange, tan and yellow, but is often mottled brown, with small black dots on the underside that help to distinguish it
