### **Day’s Leaf-tailed Gecko (*Eremnoculus dayi*)**
Identification
The Day’s Leaf-tailed Gecko is a breathtaking example of evolutionary camouflage. Reaching a total length of approximately 150mm, its body is remarkably flattened—a "depressed" morphology that allows it to vanish against tree trunks. Its skin is a rugged landscape of pointed tubercles (spiny bumps), mimicking the texture of moss and lichen. The base coloration is a mottled palette of charcoal, lichen-green, and bark-brown. The hallmark of the species is its broad, spade-shaped tail, which looks exactly like a dead, weathered leaf. To distinguish it from the similar *Saltuarius cornutus*, look at the eyes: *E. dayi* possesses massive, "dark-veined" orbs with vertical slit pupils, lacking the lighter, silvery iris found in its cousins.
Habitat & Range
This specialist is endemic to the high-rainfall "Wet Tropics" of North Queensland, Australia. It is primarily found in upland rainforests, particularly within the Atherton Tableland and the mountains surrounding the Daintree. They are most frequently encountered at elevations between 400m and 1,200m, where the humidity remains high year-round. Look for them on the mossy trunks of large rainforest trees or deep within the cool, damp crevices of granite boulder fields.
Behaviour
Strictly nocturnal and highly sedentary, this gecko is a master of the "sit-and-wait" strategy. During the day, it flattens itself so tightly against bark that it casts no shadow. At night, it adopts a characteristic head-down hunting posture. While generally solitary, they are known for their startling defensive displays; if cornered, a gecko will arch its tail, open its bright pink mouth, and emit a rasping, bird-like "bark" to startle predators.
Diet
As an ambush predator, its diet is comprised entirely of rainforest invertebrates. It favors large, crunchy prey like long-horned grasshoppers, crickets, and spiders. When a target wanders within range, the gecko lunges with explosive speed, pinned by its needle-like teeth before being swallowed whole.
Fascinating Fact
Because they lack eyelids, Day’s Leaf-tailed Geckos cannot blink. To keep their massive, light-sensitive eyes clean of rainforest debris and dust, they use their long, flat, fleshy tongues to "wipe" their eyeballs—exactly like a windshield wiper!
