Crocodilians are ancient reptiles with specific thermal, spatial and cognitive needs. Modern zoo management goes far beyond simple confinement to provide welfare-appropriate care.
Crocodilian welfare in captivity requires overcoming the assumption that their apparent stillness means contentment. These animals have specific thermal requirements that must be met through carefully designed thermal gradients — failure causes immunosuppression and digestive failure. Cognitive enrichment is increasingly recognised as important for species once considered purely instinct-driven. Feeding enrichment using varied prey presentations, scent trails and novel food items reduces stereotypic behaviour and maintains cognitive engagement. Social management must be species-specific and individually tailored — dominant individuals may prevent subordinates from accessing basking or feeding sites, requiring careful monitoring.
