How do pangolin scales protect it?
Pangolins are insect-eating mammals known for keratin scales covering much of their bodies.
Body structure, habitat and adaptation
The scales are made of keratin, the same basic protein found in human nails and hair; they are not bone or reptile scales. When threatened, a pangolin tucks in its head and curls into a tight ball, leaving hard scales outside. Strong muscles and the tail make the ball difficult to open. This defense is not always enough against large predators or humans. Appearance alone does not explain a mammal's way of life; skeleton, senses, metabolism and behavior are considered together. Individuals of the same species may differ across regions with food, climate and human pressure. Scientific observation does not treat one animal as an unchanging model for the whole species.
Behavior, ecological role and conservation
A long sticky tongue and powerful claws reach ants and termites. Lacking teeth, pangolins process food in a muscular stomach region aided by swallowed material. Illegal trade, hunting and habitat loss strongly affect them, and their scales have no proven medicinal benefit. Conservation tracks not only total numbers but also connectivity, breeding success, genetic diversity and habitat quality. Local coexistence measures, corridors and law enforcement work together. Wild animals should not be fed or treated as pets, and observation should remain at a safe distance.
