Question

Pit viper can trace its food through

• A. Sensory pits and heat radiations of prey
• B. Jacobson's organ
• C. Sharp vision
• D. All of the above

Answer 1

The correct option is A Sensory pits and heat radiations of prey

Pit vipers possess one large pit organ on either side of the head, between the eye and the nostril. In vipers, the pit organ is seen only in the subfamily Crotalinae: the pit vipers. The organ is used extensively by them to detect and target warm-blooded prey such as rodents and birds, and it was previously assumed, that the organ evolved specifically for that purpose. However, recent evidence shows that the pit organ may also be used for thermoregulation.
