๐ Q.5 IAS Prelims 2024โ Environment & Ecology (Big Cats | Animal Behaviour)๐งท Authentic Classroom Explanation by IAS Monk
๐ The Question:
Consider the following statements:
- Lions do not have a particular breeding season.
- Unlike most other big cats, cheetahs do not roar.
- Unlike male lions, male leopards do not proclaim their territory by scent marking.
Which of the statements given above are correct?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
โ Correct Answer: (a) 1 and 2 only
๐ Classroom Explanation (Statement-wise):
- Statement 1: Correct โ
Lions do not have a fixed breeding season.
Breeding can occur throughout the year and is often synchronized after a pride takeover, helping cub survival through communal care. - Statement 2: Correct โ
Cheetahs cannot roar.
Their larynx has a fixed hyoid bone structure, similar to โsmall catsโ, allowing them to purr continuously but preventing roaring.
Instead, cheetahs chirp, purr, growl, and emit explosive yelps. - Statement 3: Incorrect โ
Male leopards DO scent-mark territories using:- Urine spraying
- Faeces
- Scrape marks
- Cheek rubbing on trees
โ๏ธ Hence, only Statements 1 and 2 are correct.
๐ง Curiosity Raiser:
Why can lions roar but cheetahs cannot?
๐ Itโs not size โ itโs the hyoid bone anatomy of the voice box.
๐ Enrich Notes (Prelims Edge):
- Roaring cats: Lion, Tiger, Leopard, Jaguar
- Non-roaring cats: Cheetah, Puma, Lynx
- Territory marking is common in most big cats, including leopards
๐๏ธ IAS Monk Whisper:
โIn nature, silence can be as powerful as a roar โ survival chooses structure, not strength.โ
