Why do hyenas laugh?
Show answer & explanation
Answer: Vocalization signals stress
Imitating human laughter — Wrong. Hyenas don't imitate humans—vocalization is natural communication. High-pitched giggles signal stress, submission, or excitement.
Vocalization signals stress ✓ — Correct! Stress vocalization! Hyena 'laughter' (giggling): high-pitched series of sounds. Contexts: (1) Nervous/frightened—submission to dominant individuals. (2) Food competition—excitement/anxiety. (3) Being chased. NOT happiness! Each hyena has unique laugh—individual identification. Spotted hyenas most vocal. Complex social hierarchy—vocalizations important. Also: whoops (long-distance), growls (aggression). Misleading name—not related to human laughter. Indicates arousal/stress!
Laughing scares prey animals — Wrong. Laughing doesn't scare prey—hyenas are efficient hunters. Giggling indicates stress or excitement, not predatory strategy.
