Platypuses are among the most physiologically unusual mammals. Their welfare in captivity requires deep understanding of their specialist sensory systems, burrowing needs, and dietary requirements.
Platypus welfare in captivity is exceptionally challenging. Their electroreceptor bills require environments free from electrical interference. Stress responses are acute, and poor housing leads to stereotypic behaviour, weight loss, and early mortality. Burrow access is non-negotiable: females particularly require extensive tunnelling substrate for psychological security. Water temperature, quality, and prey availability must closely replicate riverine conditions. Only institutions with specialist expertise, large naturalistic exhibits, and meticulous husbandry should consider holding this species. Repatriation or wild rehabilitation may be preferable to substandard captive conditions.
