Satanic Leaf-tailed Gecko

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. …

The species is endemic to Madagascar, meaning it is found nowhere else. It is an arboreal animal that relies on its natural camouflage in the northern and central tropical forests of Madagascar.

A nocturnal reptile, with suitably large eyes, the leaf-tailed gecko moves about its rainforest habitat at night feeding on insects. The adhesive scales under their fingers and toes and their strong curved claws enable them to move adeptly through the trees. The leaf-tailed gecko is somewhat of an expert at avoiding predators, not only through their incredible mimicry but through a number of behaviours. They can flatten their body against the substrate to reduce the body's shadow, open their jaws wide to show a frightening, bright red mouth, and voluntarily shed their tail in order to trick a predator. Like many reptiles, the leaf-tailed gecko is oviparous, or egg-laying. Reproduction starts at the beginning of the rainy season when it lays clutches of two spherical eggs onto the ground under leaf litter or in the dead leaves of plants.

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.
