Uroplatus gecko in the Nosy Mangabe rainforest of Madagascar

Uroplatus gecko in the Nosy Mangabe rainforest of Madagascar. Leaf-tailed or Uroplatus geckos are one of Madagascar's most unique species. These moderate to large-sized geckos rely on cryptic coloration as they sleep with their head downward, flattened against tree trunks and adjusting their body coloration to their surroundings. Inactive during the day, Uroplatus geckos only move when disturbed. They respond to prodding with an impressive display of a brightly colored gaping mouth and an erect tail. At night they hunt insects.
