Tortoises are long-lived reptiles with specific thermal, dietary, and spatial needs that are challenging to meet in zoo settings. Their slow metabolism masks welfare problems that may take years to manifest.
Tortoises are sometimes perceived as low-welfare-need animals due to their slow movements and apparently simple behavior. This perception is scientifically incorrect. Their long lifespans mean that chronic welfare failures — inadequate UV-B, wrong temperature, poor nutrition, insufficient space — accumulate into serious disease over years and decades. The absence of obvious distress signals in a tortoise does not indicate wellbeing; it often reflects the stoicism of a prey species. Active indicators of good welfare include regular feeding, exploratory behavior, normal growth, and appropriate social interaction.
