Thorny Devil Katydid
Panacanthus cuspidatus

The "Kung Fu" Defense
When threatened, the Thorny Devil doesn't just sit there. it raises its front legs—which are also covered in spines—and snaps them shut like a trap on a predator’s beak or a human finger. Every inch of this insect, including its legs and head, is covered in needle-sharp spines.
Night-vision antennae
Its antennae can be three times longer than its entire body. These act as "night-vision" sensors, allowing the katydid to "feel" the "glow" of vibrations in the dark jungle.
The "Bark" Chirp
While many katydids have a musical song, the Thorny Devil produces a harsh, metallic "zip" or "click" sound by rubbing its wings together, designed to startle enemies.
