Question

Loreal pit of Vipers is______________.

• A. Thermoreceptor
• B. Gustatoreceptor
• C. Photoreceptor
• D. Phonoreceptor

Answer 1

The correct option is A Thermoreceptor

• The loreal pit is a deep depression, or fossa, in the loreal area on either side of the head in pit vipers (crotaline snakes).
• It is located behind the nostril and in front of the eye, but below the line that runs between the centers of each.
• It is the external opening to an extremely sensitive infrared detecting organ. The loreal pit is bordered by lacunal scales.
• The loreal pit also functions as part of a thermal regulating system, enabling pit vipers to maintain their body temperature.
• Hence option A is correct.
