  • Behavior and heart rate response of seven ornate box turtles (Terepene ornata) to visual threat, touch, forced diving, and voluntary diving were investigated. Visual stimulus resulted in two different behavioral and two different heart rate responses. Three of seven turtles turned and walked away from the stimulus with no change in heart rate. Four turtles stopped walking and withdrew their feet and head. Heart rate was reduced 37%. Atropine had no effect on behavior but abolished bradycardia… CONTINUE READING
