With respect to the Western Hoolock Gibbons, which of the following statements is/are correct?
- A Sanctuary in North-east India is home to this ape species listed as Endangered in the International Union for Conservation of Nature (IUCN) Red List.
- They have specialized brachiation and can easily swing between trees.
- They possess a strong and heavy build like gorillas, yet are remarkably agile tree climbers.
Select the answer using the code given below:
Detailed Explanation:
Statement 1 — Correct. Hollongapar Gibbon Sanctuary in Assam is dedicated to this species. The Western Hoolock Gibbon is listed as Endangered on the IUCN Red List.
Statement 2 — Correct. They move through brachiation — using their long arms to swing quickly from branch to branch. This is their main way of moving through forests.
Statement 3 — Incorrect. Gibbons are "lesser apes" (small apes), NOT like gorillas (great apes). They are small, slender, and lightweight — only 6 to 9 kg. Their light body is exactly WHY they can swing so agilely — a heavy gorilla-like build would make this impossible.
Memory Trick: Gibbons = Light + Long arms = Great swingers. Gorillas = Heavy + Strong = Ground-based. Don't mix them up!
