How do penguins slide on there stomachs?

Penguins slide on their stomachs, a behavior known as "tobogganing," to move efficiently across ice and snow. They use their flippers to propel themselves while pushing their bodies against the icy surface, allowing them to glide smoothly. This method conserves energy and helps them avoid predators while traveling to and from the water. The streamlined shape of their bodies aids in reducing friction as they slide.
