Did you know ... Yawning is a way for tortoises to adjust the pressure in their ears ... ? This helps them to hear better. Sometimes, they also yawn if they have excess gas in their stomachs. Our model was the victim of a devastating fire and his yawning most probable a result of a respiratory infection. #AllLifeMatters 🐢 #AllLivesMatter | Walmer Veterinary Hospital
