Another plant or animal in which you can observe wave motion?

One example of wave motion in the animal kingdom can be observed in the movement of jellyfish. These creatures utilize a rhythmic contraction and relaxation of their bell-shaped bodies to propel themselves through water, creating a wave-like motion. This efficient swimming technique allows them to navigate their aquatic environment while conserving energy. Additionally, the rippling effect of their movements can create waves in the surrounding water, illustrating the interconnectedness of motion in aquatic ecosystems.
