Crocodilians are often among the most poorly housed reptiles in zoos - their welfare requires access to deep water, basking areas, appropriate temperature gradients and adequate space for normal movement.
Crocodilian welfare in zoos is often compromised by the visual impact of large, impressive animals masking inadequate environmental provision. Small, concrete pools without depth gradients, minimal land area and no thermal options are unfortunately common. Research on crocodilian cognition reveals higher intelligence than previously assumed, with evidence of problem-solving and social learning. Enrichment through varied feeding methods, novel objects and olfactory stimulation addresses cognitive needs. Zoo accreditation bodies are increasingly requiring evidence-based minimum space and thermal environment standards for crocodilian housing.
