Pangolins are among the most difficult mammals to maintain in captivity, with specialized dietary needs, extreme stress sensitivity, and high mortality rates that raise fundamental questions about zoo keeping.
Pangolin welfare in captivity represents perhaps the clearest case in zoo keeping where the welfare evidence argues against captive exhibition for most institutions. The failure rate of captive pangolin keeping is extraordinary — the vast majority of pangolins in captivity outside of a handful of specialist facilities die within months. The causes are multiple and compounding: dietary specialization requires access to appropriate ant and termite species or sophisticated artificial diets; extreme stress sensitivity means that handling and observation cause measurable physiological distress; nocturnal and solitary behavior is incompatible with standard zoo exhibition. The handful of facilities that have achieved long-term pangolin survival — including some Chinese and Taiwanese institutions — do so through extensive investment in live food supply, climate control, and minimal disturbance. For confiscated trafficking victims, the welfare question is often whether any captive option can meet their needs.
