NARRATOR: Snakes move with an easy gliding motion, whether they are traveling on land, swimming in water, or climbing trees.
On the ventral surface of the snake's body are broad platelike scales that help it move. Each plate is connected to a pair of ribs by muscle tissue.
A snake moves by bracing these plates against the slightest roughness, while the muscles of its body push it along.
