When threatened, pangolins may release a smelly secretion from glands near their tail. The scent is strong and unpleasant, deterring many predators. Coupled with curling into a ball, this chemical defense adds another layer of protection. The secretion composition varies among species. It can irritate skin and eyes of potential threats. Chemical and physical defenses combined make pangolins extremely resilient.
It’s a second line of defense for survival in predator-rich habitats. Many predators learn to avoid pangolins entirely.
It highlights how multi-layered defenses can evolve. Chemical defense complements physical adaptations.
Pangolins’ odor has been compared to that of a skunk.
