feedback1="'''Correct!''' Gastrosteges are enlarged ventral scales on the body which aid locomotion. The number of gastrosteges may be used in snake identification [[Snake Skin|WikiVet Article: Snake Skin]]."

feedback5="'''Incorrect!''' These receptors occur in the labial pits of boids and pythons, and the heat pits of pit vipers and are used to located warm-blooded prey. Gastrosteges are enlarged ventral scales on the body which aid locomotion."
