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

Hint: Pit viper doesn’t have proper taste buds in the tongue, they have rods and cones for vision but they won't have very refined eyesight, they don’t have developed hearing aids. Their skin colour varies from patchy to fluorescent green.

Complete answer:
- Pit vipers don’t have sharp eyesight to catch the prey by seeing
- Only a few subspecies of the viper can see the ultra radiations coming out from prey few of them are vipers
- They have one pit on each eye side which helps them in catching the radiations chemically
- Chemosensory intuition in snakes is exceedingly advanced. Most snakes have a splendid experience of odour
- In part to make up for his or her terrible eyesight and confined listening to. A snake’s tongue has few flavour buds.
- Snakes use their tongues for amassing chemicals from the environment or ground. The tongue does no longer have receptors to taste or scent.
- The tongue is bifid. The tongue gathers fragrance debris from the encircling air and while the tongue is withdrawn, transfers them to a structure referred to as Jacobson’s organ for the prey trace job.
- They stumble on warm energy. Pit vipers see the sector in a combination of heat and light. The receptors hit upon heat blooded prey but can also come across bloodless blooded prey, though they may be more attentive to heat.

Hence, the correct answer is option (A).

Note: Vipers discovered in chillier, northern climates are the black or European adder have extra slight venom. Vipers discovered in less warm, northern climates where the black or European adder have extra moderate venom. They use their tongues for amassing chemicals from the environment.
