Consider the following animals:1. Hedgehog2. Marmot3. Pangolin To reduce the chance of being captured by predators, which of the above organisms rolls up/roll up and protects/protects its/ their vulnerable parts?
✓ Correct answer: d) 1 and 3
ExplanationOption 1 is correct: Hedgehogs are small mammals with short limbs and a body low to the ground.Their most dis- tinctive characteristic is the thousands of stiff, sharp spines - harder and sharper than those of a porcupine - that cover the animal’s back and sides, like a pincushion filled with needles.If attacked they will curl into a prickly and unappetizing ball that deters most predators.Option 2 is incorrect: Marmot are any of 14 species of giant ground squirrels found primarily in North America and Eur- asia.Marmots are well suited for life in cold environments and have small fur-covered ears, short, stocky legs, and strong claws for digging.Marmots do not roll up and protect their vulnerable parts.They often use their sharp teeth and powerful jaws to defend themselves.Option 3 is correct: Pangolin, also called scaly anteaters be- cause of their preferred diet.They are the most trafficked mam- mal in the world.If touched or grabbed it will roll up completely into a ball, while the sharp scales on the tail can be used to lash out.Environment and Ecology 521 204
