Reptiles differ from other exotic animal species in fundamental ways that shape how they interact with their environment and directly influence their veterinary experience from physical exam to therapeutic interventions. Understanding these differences is essential for effective and appropriate veterinary care. This lecture will review key anatomic and physiologic features that have the greatest impact on clinical management of reptile patients. Topics will include ectothermy, integumentary adaptations, and cloacal anatomy. Clinically relevant musculoskeletal features will be discussed, including the chelonian shell as part of the skeletal system, kinetic skeletal characteristics of snakes and lizards, and caudal autotomy. Cardiorespiratory features including asymmetric lung anatomy in snakes, cardiac shunting, and renal and hepatic portal circulation will also be reviewed. Common clinical scenarios will be used to demonstrate how these reptile-specific features alter physical exam findings, diagnostic planning, and therapeutic decision-making. Attendees will leave with a clearer understanding of how reptile anatomy and physiology shape veterinary care and how to apply this knowledge in clinical practice.
