What is unique about the thorny devil's defense mechanism?

• A. The thorny devil roars loudly to deter predators.
• B. It sprays ink when threatened.
• C. It uses venom to deter attackers.
• D. Its spiny body deters predators.

Answer: (D)

Spiny armor acts as the defense. The thorny devil is covered in sharp spines that form a protective barrier, making it hard for predators to bite, grab, or swallow it. That physical deterrent means attacks are costly for the predator, so many will back off rather than press in. This strategy stands apart from ideas like roaring, ink spraying, or venom, which aren’t used by this species. The combination of the rugged, spiked exterior and desert camouflage helps it stay safe, with the spines being the standout defensive feature.
