The role of the vomeronasal organ of crotalines (Reptilia: Serpentes: Viperidae) in predator detection
Article Abstract:
It is clear that the vomeronasal organ plays a significant role in the ability of crotaline snakes to detect the presence of kingsnakes, according to research designed to test the hypothesis that the defensive response of crotaline snakes is mainly mediated through the detection of skin-derived semiochemicals by the vomeronasal system. This research involved testing pit vipers for the presence of one or more defensive behaviours. It is not likely that other methods of detection, such as touch and sight, play a role in recognition of kingsnakes.

Antipredator behaviour of hatchling snakes: Effects of incubation temperature and simulated predators
Article Abstract:
Emerging reptile hatchlings are vulnerable to predators, particularly during daylight. The response of pine snake, Pituophis melanoleucus hatchlings to visual and vibratory stimuli was studied, to assess antipredator behaviour. Hatchlings were more protective than defensive and responded with less intensity to vibration, compared to visual stimuli. It is indicated that those incubated at medium temperatures are likely to be less vulnerable to predators than those incubated at higher or lower temperatures.

Feeding responses in young boa constrictors are mediated by the vomeronasal system
Article Abstract:
The vomeronasal system controls the feeding responses in Boa constrictor imperator. The snakes use infrared reception to detect prey odour which determines the feeding behavior. In the absence of thermal and tactile signals, prey odours and intact vomeronasal system are required to evoke the feeding responses. Airborne chemicals increase the tongue flick rate in the boa constrictors which is an important factor in mediating the feeding response.
