Prelims 2021 · Environment · Question 23
Consider the following animals:
- Hedgehog
- Marmot
- 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?
Answer
1 and 3
Hedgehog — Hedgehogs curl into a tight ball, using their spines to shield the soft underside from predators. Correct.
Marmot — Marmots mainly escape predators by running into burrows and using vigilance calls; rolling up is not their typical defense. Incorrect.
Pangolin — Pangolins roll into a ball, protecting vulnerable parts with their hard keratin scales. Correct.
Hence, 1 and 3 are correct.
