Why in News
- International researchers have officially revalidated the Himalayan pangolin (Manis aurita) as a distinct species rather than a subspecies of the Chinese pangolin (Manis pentadactyla).
About the Himalayan Pangolin
- The Himalayan pangolin is a unique scaly mammal that belongs to the Manidae family.
- It is a night-active insect-eater that relies heavily on smell to keep forest insect populations balanced.
Habitat and Distribution
- This species lives exclusively in the southern Himalayan foothills across Nepal, South Tibet, and Assam in Northeast India.
- Natural barriers such as the Brahmaputra River basin and the Arakan Mountains separated this species from other Asian pangolins for millions of years.
Physical Attributes
- Overlapping keratin scales form armor over its body when the animal rolls into a tight ball for protection against predators.
- It features a large body and skull structure with an average total length of 95.2 cm.
- Despite its large size, it has noticeably small and reduced outer ear rims.
- It possesses a shorter and broader nasal bone structure compared to its lowland relatives.
Behavioral and Reproductive Traits
- This solitary animal stays hidden inside deep underground burrows during the day and comes out only at night to forage.
- Because it has poor eyesight, it uses its enlarged olfactory bulb and acute sense of smell to locate underground ants and termites.
- Its long curved front claws allow it to rip open hard soil mounds and dig deep nesting tunnels effortlessly.
- Female pangolins reproduce slowly and usually give birth to only one pup after a long pregnancy.
- Newborn pups have soft scales and ride on their mother's tail until their protective armor hardens completely.
Key Differences: Himalayan vs. Chinese Pangolin
- The Himalayan pangolin features smaller reduced ear rims, whereas the Chinese pangolin has noticeably larger external ears.
- The Himalayan pangolin has a shorter and broader nasal structure, while the Chinese pangolin has a longer and narrower nasal bone layout.
- The Himalayan species diverged within cold and arid Himalayan refuges, whereas the Chinese species evolved in stable southern forests.
- The Himalayan pangolin shows acute inbreeding spikes in localized pockets, while the Chinese pangolin experiences widespread baseline inbreeding.
