Giant Leaf-tailed Gecko
Uroplatus fimbriatusAlso known as Common Flat-Tail Gecko, Madagascar Leaf-Tailed Gecko, Fringed Leaf-Tailed Gecko
Giant leaf-tailed geckos spend their days motionless on tree trunks, resting head-down while dermal flaps along their body flatten to erase any shadow on the bark. When disturbed at night, they open their bright yellow mouths wide and utter a startling, high-pitched scream to deter predators. Females lay pairs of spherical, hard-shelled eggs in leafy litter on the rainforest floor.

Interaction riskLow
- Low
- Moderate
- High
- Very high
- Why interaction risk is low
- Capable of a painful defensive bite if cornered; observe quietly from a safe distance.
- Why it is dangerous
- Possesses strong jaws and sharp teeth capable of breaking human skin during a defensive strike.
- How to recognize a risky encounter
- Recognized by its broad flat tail, mossy skin patterning, and wide mouth with a bright yellow lining.
- What to do
- Avoid touching or grabbing the gecko, as cornering it triggers a gaping vocal threat display and bite.
- What to notice
- Identified by a moss-like bark pattern and broad, notched tail flattened against rainforest trunks.
- Support conservation
- Keep light beams brief when observing at night and leave the surrounding vegetation undisturbed.
Responsible observation
- Night spotting: Search vertical tree trunks in primary rainforest using a soft flashlight after dark.
- Observe camouflage: Keep a respectful distance to watch how the skin fringe blends with lichens.
