Yes, do penguins have knees, but they are not externally visible. Penguin legs are adapted for swimming, with short, stout bones that are well-suited for propelling them through the water. The knee joint is actually located close to the body, hidden beneath the feathers. What may seem like their lower leg is, in fact, their foot, and they walk with a distinctive waddle due to this unique skeletal structure. While their knees serve a vital function in their anatomy, they are not prominently displayed, contributing to the streamlined and hydrodynamic shape of their bodies for efficient underwater movement.
