Nosy Be flat-tail gecko

Description

Uroplatus ebenaui, commonly known as the spearpoint leaf-tail gecko or Nosy Be flat-tail gecko, is a species of lizard in the family Gekkonidae. U. ebenaui is found on Nosy Bé island and in eastern and northern Madagascar. The specific name, ebenaui, is in honor of German zoologist Karl Ebenau. U. ebenaui lives in tropical rain forests and dry deciduous forests. U. ebenaui is the smallest species of Uroplatus and can reach a total length (including tail) of 4 inches. U. ebenaui is arboreal and nocturnal. This gecko eats insects at night and is inactive during the day. Additionally, they sleep flattened against tree trunks to camouflage in with the bark. Uroplatus ebenaui may be a complex of species. Uroplatus is a genus of geckos, commonly referred to as leaf-tail geckos or flat-tailed geckos, which are endemic to Madagascar and its coastal islands, such as Nosy Be. They are nocturnal, insectivorous lizards found exclusively in primary and secondary forest. giganteus to 10 cm (3.9 in) for U. ebenaui. Larger species of Uroplatus are distinguished among geckos in having the largest number of marginal teeth among all living amniotes. Other rare apomorphic character states include multiple inscriptional ribs, restriction of autotomy planes, and finger-like diverticula of the lungs. All Uroplatus species have highly cryptic colouration, which acts as camouflage, most being grayish-brown to black or greenish-brown with various markings resembling tree bark. There are two variations of this camouflage: leaf form, and bark form. The leaf form is present in a number of small-bodied species. All other forms blend in well with tree bark upon which they rest during the day. Some of these tree bark forms have developed a flap of skin, running the length of the body, known as a "dermal flap", which they lay against the tree during the day, scattering shadows, and making their outline practically invisible. These geckos bear a resemblance to geckos of the genera Phyllurus and Saltuarius of Australia. This is an example of convergent evolution. The skull of Uroplatus is strongly ossified, with an extremely high tooth count and incipient secondary palate. The genus Uroplatus has had a complex taxonomic history. However, the most recent and detailed study suggests there are at least 11 undescribed cryptic species in the genus, several of which have been described since its publication in 2013.
