Why do penguins waddle?

Energy conservation is an important element of survival for animals in the icy country. For example, the way to wiggle and wiggle like a penguin is a clever way for them to achieve it.

Dr. Rodger Kram (University of California, Berkeley, USA) performed experiments on emperor penguins at San Diego Sea World Park. Five penguins were walked through a special yard to measure the force they used when swaying.

Accordingly, with penguins, walking is ' energy wastage ' because they have too short legs and have to produce energy as fast as muscles to transfer to these legs. However, penguins have found an optimal way of balancing people to the sides. The waving motion of the penguin is similar to the movement of a pendulum.

When leaning to each side, their body's center of gravity is raised. Because without this movement, the muscles will have to do it. This way of moving helps penguins save energy.
