Mossy Leaf-tailed Gecko
Uroplatus sikorae · also called mossy leaf-tailed geckos
Motionless against a lichen-covered trunk, a mossy leaf-tailed gecko blends so completely into the bark’s mottled pattern that it can be nearly impossible to spot, even for someone who knows exactly which tree to search.
Overview
The mossy leaf-tailed gecko, Uroplatus sikorae, is a Least Concern reptile endemic to humid rainforest across parts of eastern Madagascar. Its mottled moss-and-lichen camouflage, flattened fringed body, and tendency to closely match its specific home tree make it one of the most effectively disguised reptiles found anywhere.
Camouflage tailored to a single tree
Rather than a generic bark pattern, individual mossy leaf-tailed geckos often closely resemble the particular tree they typically rest on, a level of camouflage precision that suggests the gecko benefits from staying loyal to one familiar spot.
Status
Least Concern, remaining present across suitable rainforest habitat in eastern Madagascar, though affected by habitat loss and collection pressure for the exotic pet trade.
Mossy Leaf-tailed Gecko: common questions
How good is the mossy leaf-tailed gecko's camouflage?
Exceptional; its mottled green, brown, and grey skin pattern so closely mimics moss and lichen on bark that individuals can be genuinely difficult to spot even when someone knows roughly where to look.
Does the mossy leaf-tailed gecko always match the same tree?
Often, yes; individuals tend to closely resemble the bark pattern of the specific tree they typically rest on, suggesting the camouflage works best when the gecko stays faithful to a particular spot.
Is the mossy leaf-tailed gecko active during the day?
No, it remains motionless and hidden by day, relying entirely on its camouflage, and becomes active at night to hunt insects and other small invertebrates.
Where is the mossy leaf-tailed gecko found?
It is endemic to humid rainforest habitat across parts of eastern Madagascar.
