Which term refers to a wave-like motion used by snakes for movement?

• A. Hibernate
• B. Undulation
• C. Ambush
• D. Pigment

Answer: (B)

Snake movement often relies on rhythmic bending that creates traveling waves along the body. The term for that wave-like motion is undulation. When a snake undulates, waves of curvature travel from head toward tail, and different body segments anchor or push against the surface while other segments propel the head forward. This wave propagation is how the snake converts muscle activity into forward motion, especially in lateral undulation on flat ground or in water. Hibernate means sleeping or entering a dormant state, ambush is a predatory strategy, and pigment refers to color or pigment-producing substances. None of those describe a motion pattern, which is why the wave-like bending term is the correct choice.
