Consider the following animals : 1. Hedgehog 2. Marmot 3. Pangolin To reduce the chance of being captured by predators, which of the above organisms rolls up/roll up and protects/protect its/their vulnerable parts?

Hedgehogs and pangolins are biologically adapted to roll into tight balls, using their spines and tough scales respectively to shield their vulnerable underbellies from predators. Marmots, while often confused with other small mammals, are large ground squirrels that rely on alarm whistles and retreating into burrows rather than rolling up for defense. The core concept tested is the specific behavioral and physical adaptations for predator avoidance in terrestrial mammals.
