Answer: C
Notes:

Explanation: All snakes smell with their tongues. When a snake sticks out its tongue it smells its surroundings.

  • The moist tongue collects scents and small organisms from whatever it touches and from the air around it.
  • When the tongue goes back into the mouth the forks touch a special sensory spot called the Jacobson’s organ on the roof of the mouth and tell the snake what it smells.
  • Snakes have a small notch in their lips that they can stick their tongues through, so they don’t need to open their mouths. Some snakes can smell with their noses.
